We have been intrigued by the life story of Hannah Slater, listed in Mt Zion Methodist church records as well as District of Columbia death records as the longest living persons buried in the Mt Zion-Female Union Band Society cemeteries in Georgetown, Washington DC. Her death is recorded as July 15, 1878, and her birth year as 1768, which would give her a life span of 110 years. This seems improbable. What can be inferred about her life and likely year of birth?
Her death record in Joseph Birch’s undertaker book as well numerous entries in the District of Columbia city directory indicates that her residence was 32 Beall Street, Georgetown (now 2617 O Street), which was also the home of Clement Beckett ( b 1815) and his wife Mary Beckett (1814-1894) for many years. This is now just across from the Rose Park pickleball courts.
Clement and Mary Beckett played important roles in the foundation of Ebenezer African Methodist Episcopal Church, which was formed by Black members who left Mt Zion Methodist in 1856. (Ebenezer AME left Georgetwon for Fort Washington, MD in 1983). The death certificates for Clement and Margaret’s sons Clement Wainwright Becket and Joseph Cartwright Becket and daughter Margaret Beckett Ferguson (d. 21 April 1928) all indicate that Mary’s maiden name was Slater, the same surname as Hannah. Hannah was thus clearly the mother of Mary Slater Beckett and the mother-in-law of Clement Beckett.
Indeed, the first census record for Hannah Slater, in 1850, shows “H Slater”, a free woman of color, age 70, residing in the household of “C Becket” (Clement Beckett). age 35 and M Becket (Mary Beckett), age 34 in Georgetown.

I do not see Hannah Slater in the 1860 census. The 1870 census records Hannah Slater, age 98, that is to say born 1772, residing next door to Clement and Mary Slater, in the home of John H Ferguson, waiter, and his wife Margaret A Beckett Ferguson, who had married four years earlier, on 30 August 1866.
Margaret is the daughter of Clement and Mary Beckett and the granddaughter of Hannah Slater. The 1880 census, two years after the matriarch Hannah’s death, shows Clement and Mary and their son in law John H Ferguson and daughter Margaret A Beckett Ferguson, all residing in the same household.

The 1864 DC city directory lists Hannah Slater as colored, widow of Benjamin, boarding on L street north, near 23rd. The 1878 and 1879 city directories lists her as residing as 32 Beall in Georgetown, also as the widow of Benjamin Slater.

Who was Benjamin Slater, the late husband of Hannah, who must have died prior to 1864?(The fact that Hannah Slater was living with her daughter and son in law in 1850 may imply that Benjamin died earlier than that year.) There is no record in the 1840, 1850 or 1860 census of a free Black man named Benjamin Slater, which may imply that Benjamin was enslaved.
Perhaps relevant: a Benjamin Slater was emancipated in Maryland on 1 November 1864 under the terms of the new Maryland Constitution; in 1867, the heirs of William C Pearce of Montgomery County MD unsuccessfully filed for compensation for his freedom. William C Pearce in 1860 owned 24 slaves in Medleys District, Montgomery County, MD and one slave in Georgetown. (Medleys District was located along the Potomac River and the C & canal in the vicinity of modern day Seneca and Poolesville).
The November 1866 Freedman’s Bureau notebook, which retroactively records Black marriages, notes that in 1834 a presumably different Benjamin Slater married an Elizabeth Ricks in Washington DC.
This may be the same Benjamin Slater born about 1800 listed in the 1870 census, residing with Caroline Slater, age 48, residing next door to Francis Slater, hotel waiter, age 27.

Perhaps this Benjamin Slater was the son or different relation of “our” Hannah Slater.
In any event, I have not located a newspaper death notice or obituary for Hannah Slater, although, as noted above, her death, on 15 July 1878, is recorded in Mt Zion Church records and the Joseph Birch undertaker notebook. Her burial on 17 July 1878, is recorded in the Register of Burial, Colored, District of Columbia.

If her age of 70 enumerated in the 1850 census is correct, then Hannah was born around 1780 and died at the age of 98 in 1878. This is still an age of impressive longevity but not quite the 110 years listed in the DC death records.
Remembering Hannah’s daughter and granddaughter in the FUBS Cemetery
Hannah’s daughter Mary (Slater) Beckett is memorialized by the standing monument
in Section 9 of the Female Union Band Society cemetery, with the inscription:
In loving
remembrance
of our dear mother
MARY BECKETT.
Died July 29, 1894
Aged 80 years
3 months and 9 days.
Gone but not forgotten
Our Mother is gone and we are left. The loss of her to
mourn. But may we hope
to meet with her with Christ
before his throne.
Hannah’s granddaughter Margaret Beckett Ferguson is memorialized, with her father Clement Beckett on the other side of the monument:
IN MEMORY OF
CLEMENT
BECKETT
DIED DEC 1, 1901
AGED 92 YRS.
MARGARET BECKETT
FERGUSON
1845-1928
Hannah Slater perhaps is interred near her daughter and granddaughter, but I am not sure of this.
Enslaved Background of Hannah Slater and Mary Slater? The Orme’s and the Slater’s
Hannah Slater, as noted above, was a free woman in Georgetown as early as 1850. Was she born free or enslaved?
“Hannah” may be referenced in the 1829 will of James Orme of Montgomery County, which bequeaths to his wife Rebecca (Brightwell) Orme, three slaves, including a woman named “Hannah”:
I give and bequeath unto my dear wife Rebecca Orme… during her natural life my three colored people called Tom, Hannah, and Henrietta, after and from the time of my said wife’s decease it is my will and I hereby ordain that the said colored people Tom, Hannah and Henrietta, shall be manumitted and made free.

Rebecca Brigthwell Orme was still alive in December 1836 when she published in the newspaper her intention of moving west and selling the farm of her late husband James, 12 miles from Washington DC. I have not yet located a death record for her; presumably, after her death, Hannah, Tom, and Henrietta became free.
Although the will does not specify the surname of the enslaved “Hannah,” there is some indirect evidence that her surname might have been “Slater.” In the same 1829 will, James Orme of Montgomery County specified:
I give and bequeath to my third son Patrick Addison Orme my three colored people, Jasper Wesley and Eliza , the boys Jasper and Wesley to serve until they arrive at the age of thirty five years, and the girl Eliza until the age of thirty years. from and after which time they three shall be manumitted and free,

This Eliza almost certainly later became Eliza Slater (1828-1926), later Eliza Slater Wilson, who as of 1859 was attested to be a free woman of color by a Patricia Johnson in the District of Columbia; two years later in 1861 she married Clement Wilson. Her daughters Marion Wilson, age 14, and Henrietta Wilson, age 11, remained enslaved as the property of George Orme until DC emancipation on 16 April 1862, after which George Orme claimed compensation for them. George Orme attests he received the two girls from Jeremiah Orme, who in turn inherited their mother from James Orme.
The Mt Zion-FUBS Cemetery Information System records that Mary Slater Beckett was the former slave of Jeremiah Orme of Montgomery County and Georgetown. I have not seen direct evidence of this manumission yet. However, James Orme did clearly in 1828 bequeath to his son Jeremiah Orme two slaves, the boy Gassaway and girl Polly, the former to be manumitted at age 35 and the latter to be manumitted at age 30. (Gassaway seems likely to have become Gassway Thomas, who in 1880 was residing at 51 Beall Street in Georgetown, a few doors away from Hannah Slater and her daughter Mary Slater Beckett and son in law Clement Beckett.)
Jeremiah Orme did manumit his slave Edward Lancaster in 1811. (MONTGOMERY COUNTY COURT (Land Records), Liber P, Folio 266, 1810-1812, [MSA CE 148-16]. Jeremiah Orme to Edward Lancaster, July 9, 1811. Deed of Manumission.)
So, tentatively, it seems reasonable that Hannah Slater was enslaved by James Orme and inherited by his widow Rebecca Brightwell Orme and then freed after her Rebecca’s death, which would seem to have happened before 1850
I am not sure if Hannah Slater late husband Benjamin Slater was free or enslaved at the time of their marriage.
We hope to learn more about the life of Hannah Slater and her relations in Georgetown and environs.
