Primus & Mary Slocum’s Afro-Wampanoag Legacies

Primus Slocum was an African American veteran in a pioneering Revolutionary War unit who became a key ancestor to contemporary Seaconke Wampanoag people and, through adept real estate speculation, purchased land that he and his wife Mary built into a family ‘homestead’ populated by their descendants for generations. This land purchase and subsequent bequest to their children shaped the neighborhood where several of their descendants live today.

Primus Slocum was born c. 1755 in Rehoboth, Massachusetts1,2. He was likely born enslaved and one hypothesis tells us that his enslaver was Isaac Howland (b.1726. d. 1811).3 Howland was a member of the large Dartmouth-area Quaker community which also contained several wealthy slaveholding Slocum families. By the 1770s, New England Quakers took a fervent anti-slavery stance. The Dartmouth meeting hounded members to free their enslaved people and in January 1777 Howland manumitted a man named Primus.4

The connection to Howland, of course, is speculation and there could be several plausible hypotheses as to where Primus spent his early years and where his surname came from. It’s fair to speculate that Primus was familiar with the family of Paul (Slocum) Cuffee, the African-Wampanoag merchant and civil rights activist, and perhaps Primus may have once been enslaved by Quaker widow Rebecca Slocum of Dartmouth. It is further plausible that Primus spent some early years in Newport, Rhode Island.

“Isaac Howland 2nd gave in a bill to this meeting Manimiting a Negro man named Primus but yet Some friends Doubting wheather S.d Negro is fully freed therefore S.d matter is Refer’d under the care of the Same Committee as heretofore & they to Report next mo meeting.” 3
Dartmouth, MA: Quaker Meeting Minutes. January 1777.

But what is known is that in 1785 we find Primus Slocum in nearby Rehoboth, Massachusetts, getting married. There are two records for Primus in the Rehoboth Vital Records: a June intention to marry Mary Alibine and an August marriage to Mary Cleburn.5 At this time it is unknown why there is a discrepancy. It is possible that Mary Alibine and Mary Cleburn are two different people, and it’s also a possibility that Mary, who is noted as “negro” in the record and believed by family tradition to be Wampanoag, was known to the English by multiple family names. Perhaps one name is a mistranscription or perhaps Mary, about age 28 in 1785, had been married before and one surname is her maiden name and the other name is that of her first husband? Many Wampanoag women were listed as widows at the end of the Revolution.6

Seekonk’s Cushing Conservation Area lies on or adjacent to land once owned by Primus and Mary Slocum.

Records further show that Primus and Mary had three children: Jerimiah, Elizabeth, and Susan.7,8 In the 1790 U.S. Census, Primus appears in Rehoboth with 5 people in his household.9 In the 1820 U.S. Census, Primus appears in the newly-incorporated Seekonk (formerly the western parish of Rehoboth), but it is impossible to see if there are other people of color in his household.10

Revolutionary War Veteran

Excerpt from Revolutionary War Record Book, First Rhode Island Regiment, 1781-1783. Rhode Island State Archives. Here, Primus’ place of birth is listed as Rehoboth. See .pdf page #46.

Primus was a musician. We know this because Primus Slocum was a Revolutionary War veteran: first, at age 22 in the Massachusetts militia for the town of Rehoboth (in September of 1777, the same year as his possible manumission),8,11,12 and later, on Christmas Day, 1780, enlisting as a professional soldier in the famed 1st Rhode Island Regiment known as the “Black Regiment.” 6,13,14 Primus was enticed to cross state borders to join the regiment by a yearly cash bonus, called a bounty, of “100 silver and 6000 continental dollars” promised by the town of Providence.15 The 1st Rhode Island was the first regiment to be composed of all African, Indian, and multi-racial soldiers; all other units were integrated.16 The regiment received a posthumous Congressional Gold Medal in 2022.17

Original discharge for Fifer Primus Slocum. 25 Dec 1783. 1783 is the same year that slavery was ruled unconstitutional by the Massachusetts Supreme Judicial Court.

Primus’ job in the Continental army was fifer. Dr. Judith Van Buskirk notes that “[t]he best-paid position a man of color could hold in the continental line was that of fifer or drummer.”18 Fifers and drummers were non-combat positions that assisted commanders in directing troop movements. It was easier for a company to hear the continuous pitch of the fife or the beat of the drum than it was to hear singular verbal commands.

By examining Primus’ Revolutionary War pension file closely, it conveys that Primus was proud of his position. As Van Buskirk notes, Primus remembers the exact date of his promotion to fifer. And 35 years after the war’s end, he still had his discharge (posted above) and it was in very good condition.

We learn from an 1820 pension filing that his wife Mary is still alive and aged 63 and, furthermore, Primus states that he was a property owner holding “one acre of poor land and seven acres of old field land” worth $85 dollars. This statement in Primus’ pension file leads us to the Bristol County Registry of Deeds which reveals Primus and Mary were involved in six real estate transactions in Rehoboth/Seekonk spanning the years 1803-1824.notes 19 – 26

Another striking feature of Primus’ pension file is that his service narrative was written in his own hand and Primus’ signature appears several times. Many of the African-descended and Indigenous soldiers could not write English and could only mark an ‘X’. In viewing Primus’ literacy in parallel with his skill as a musician, it is clear that he grew up in a household that educated him and he leveraged those advantages as a free man.

Signature of Primus Slocum

Primus died in Seekonk in 1836 and was cared for enough by family and community to rate a death notice mentioning his Revolutionary War service.1,8,27,28 The notice appeared in papers from Boston to Providence and to New York City.

Primus Slocum’s Death Notice, 4 Nov 18261

Chestnut Street, Seekonk

Above: 1850 map showing the Chestnut Street home of Marcus A. Elderkin and Betsey Slocum Elderkin. (Walling, H. (1850). Detail: Map of the Town of Seekonk.)
Below: Present-day Chestnut Street

The Wampanoags, or the People of the First Light, are the Southern Massachusetts/Rhode Island first nation peoples that were displanted by both the Pilgrims and the founders of Providence Plantations. And while the Massachusetts town of Seekonk had been Seaconke Wampanoag homelands for millennia, tribal identification was outlawed following King Philip’s War, and systems of genocide, slavery, and debt peonage restricted Wampanoag participation in the English-created system of land ownership.

A transcription of an 1842 document that resides with the Bristol County Registry of Deeds shows Primus and Mary’s Seekonk land (adjacent to Chestnut Street) being divided by Betsey Slocum and husband Marcus Elderkin, and Betsey’s siblings Jerimiah and Susan.30,31 Primus Slocum, partly because of the financial advantages gained through Revolutionary service, and through his marriage to Mary Cleburn, serendipitously assisted in the return of a small portion of ancestral land to Seaconke Wampanoag people. This property remained the Elderkin family “homestead” for 150 years and a number of families descended from Primus and Mary Slocum live close to the Chestnut Street property today.

Excerpt from a 1999 Seaconke Wampanoag publication describing the importance of Chestnut Street to the Elderkin clan.31

What is further notable about the Slocum-Elderkin homestead is that Primus built it with a partner. Mary Slocum’s name appears next to Primus on each of the real estate transactions, including an 1824 sale when Mary would have been aged 67. Indian and African families are naturally matrifocal and one cannot help but recognize that, because the family maintained generational affection and loyalty to this plot, Mary Cleburn Slocum must have been the north star for her children. Women and domestic labor have long been excluded from the record, but government documents are not required to conclude that, for this enclave to survive for centuries, Mary certainly put in tremendous work to create an indelible sense of “home” for her clan.

And what about Primus’ service to a country that withheld love and harbored hostility to his kin and community for generations? Primus was clearly proud of his patriotic efforts, but patriotism is not necessary to celebrate his Revolutionary service. In Primus’ story of struggle and survival, the Revolution was a crucible. Primus leveraged the transformative power of the American Revolution to put bond slavery in the rearview mirror and, with his wife, he started a family, earned wages, bought property, and created a durable homestead space for generations of kin and community. And that will always be worth celebrating.

    Hi Wayne,
    My name is Mike Markley. I think the ENP article is written very well and you have a treasure trove of information. Did you do your own research and discovery of this information?
    I am the tribal historian for the Seaconke Wampanoag tribe. Almost all of the info in your article I researched and provided the tribe many years ago. Some of the info in your article I wrote myself.
    I am of Slocum/Elderkin decent. Primus is one of my Grandfathers 6 generations back. Do you plan on any other articles on these families?

      Hi, Mike –

      Thank you for reading and commenting. Yes, I recognized your name because, as you see above and point out, I excerpted your work to help connect the story to present-day Chestnut Street. That .pdf helped me truly understand the profound impact of Primus and Mary’s legacy.

      And yes, I researched this from scratch, building on work done by you and others and also surfacing other information not published elsewhere online. Your 6x great-grandparents left an incredible story; it was a thrill to learn and write about it, and it’s amazing that they left such a paper trail.

      I don’t plan to write further on your family unless I find new information that pre-dates the Revolution, as I generally write about life during the time of slavery in Mass.

      By the way, I didn’t know this in July when I published this article, but there are high-quality images of Primus and Mary’s deeds available at FamilySearch. I haven’t gotten a chance to update, but here is one example and maybe they’re useful to your efforts:

      Thanks again for reading, Mike!
