He and his descendants would come to own over seven plantations making up Oxon Hill on the Eastern Branch and over 20,000 acres of Maryland in total. Addison was the first man to patent lands inside of what became the District of Columbia. He led Maryland’s glorious revolution and was business partners with Queen Anne of England.

The Colonial Addison Family

Col. John Addison had three sons and a daughter. By his wife Rebecca Wilkinson he had, Col. Thomas Addison (1679-1730). Thomas spent his life following the footsteps of his father. At the age of 18 Thomas was elected as the colonial surveyor. Like his father before him, he served in the Upper and Lower House almost his entire adult life. One of Thomas’s biggest accomplishments was his ability to take the 6,000 acres left to him from his father and expand that estate to over 20,000 acres. No other descendant of this family would every expand on the family’s estate, they would only cultivate what Thomas had achieved. Thomas married twice to, Eleanor Smith and Rebecca Tasker. By them he had six children, Maj. Thomas Jr., Capt. John, Rev.

Rev. Addison was also President Washington’s good friend. Washington’s step-son Jack Custis attended Rev. Addison’s school led by Jonathan Boucher in 1768. President Washington’s nephew Nathaniel Washington lived on Rev. Addison’s estate in 1789, and Rev. Addison’s brother Capt. John Addison sold the larger portion of Mt. Vernon to President Washington. In 2017, the Smithsonian Institute revealed some of the family’s Black descendants.

Washington’s wife Martha Washington had a black half-sister. Rev. William Henry Addison also had three Mulatto children and the presence of Black relatives could have pushed these founding fathers into establishing a way to free their family. This picture called the Washington family depicts an unknown free Black man related to Washington’s wife. During the turn of the century around the 1790’s Washington and his Addison relatives pushed for the freedom of their slave relatives.


Addison’s Emancipation

Another relative and close friend to President Washington was Rev. William H. Addison’s nephew’s Rev. Walter Dulany Addison. Rev. Walter took over the rectorship of St. John’s after his uncle Rev. William. He also established the first church in Washington, DC as St. John’s in Georgetown. Rev. Walter preached at President Washington’s funeral and was the biggest slave abolitionist in the State of Maryland. He was the US Senate Chaplain and he, his brothers and their cousins freed all their slaves during the formation of the new capitol city.

The Addison family has owned the Chechester land tract for over 300 years, starting with Col. John Addison. The tract consist of 887a. and was inherited by Rev. William Henry Addison in 1727. In 1764 Rev. Addison patented it for his heirs, and in 1789 it was inherited by his son Anthony Addison. In 1800 Anthony received a reclamation letter from Prince George’s County for the Chechester. In 1810 Anthony then created a trust for his sons Robert, William, Thomas and Charles Addison which included the Chechester and the non patented Stanton Town lands. The Anacostia Smithsonian wrote that Stanton Town, started by the Black Addison family was the first affluent black neighborhoods in the District of Columbia. In 1867 the Freedmen’s Bureau built Potomac City on the Chechester with Jacob Moore. This 1873 map shows the black descendants of Anthony Addison in Stanton Town. Anthony’s father originally purchased this tract in in 1776.


The Story of Chechester In 1860 Robert Addison established his estate on the Chechester at Good Hope Hill. His brothers Robert’s three brothers all lived down down the road in Stanton Town. The Black Smith, Hall and Hanson families intermarried with them and their descendants and founded the community around 1850.

Lemuel Robert Addison

Robert and his wife Sarah Addisons son Rev. William Henry Addison II pastored Allen Chapel AME and St. John’s Colored parish in the late 1800’s. Both churches were established by the family. In 1867 Robert’s nephew-in-law Jacob Moore built Potomac City with President Lincoln’s war secretary, Edwin Stanton. The Black Moore family were slaves to the colonial Addisons and are related to the Black Addisons and Smiths. Jacob Moore’s granddaughter Mary Ellen Moore Addison, an original investor in the Industrial Bank of Washington married Lemuel Robert Addison, grandson to Robert Addison and great grandson to Anthony Addison. Together they inherited the family’s estate on the Chechester. Jacob Moore Cemetery Plot Map, 1900

Washington, Addison & Carter

Christian’s DNA Result to Samuel Washington & George Washington Carter of the George Washington Family.

In 2016 the National Smithsonian wrote an article titled, ‘George Washington’s Family Tree is Biracial.’ The article discussed multiple Black women including those from the Carter and Branham families of Virginia. The article detailed the Black Carter wedding at the Arlington House which is currently the site of the Arlington National Cemetery. The Carter and Addison family’s biracial family lines have been DNA tested and linked to the Washington family of President Washington’s niece, Elizabeth Lewis Carter. Christian Carter Addison’s DNA test above shows his relation to the descendants of Elizabeth Lewis Carter and the Washington family of President Washington. Christian is also related to the Washington family through his great great grandfather, Lemuel Robert Addison.

IAM G

Washington, you know I’ll always be watching them, and you never told a lie so neither will I. For without a why there is no I, I mean no eye, no I really mean no Áy. Washington, we were meant to exemplify your hymn and you know why. See my mummy always showed me to reach for the sky. Washington, they know all about you and I. Oh I believe in a new beginning which shall never die. Washington, we won’t end, for with these patents thou shall never win. Washington, I now see clearly all your enemies, but I’m G like he who sits on the capitol’s beam. How they let young Addison dream? Not afraid to say I’m Washington’s real black history. See I’m freee with a triple e. Washington, Carter and Addison really lives through me. Oh sweet Mona Lisa, straight from the mouth of Giza, ask yourself why would they release you? When some don’t even see us as people, let alone be a common equal. They say Jesus made us all believers, but we too have Jesus features, filled with hansom features. See Washington I’ll always be watching them, So it’s from DC to Maryland, then to Virginia and back again. - Christian Allyn C. Addison Sr.


‘I know of John Addison, and how he acquired most of the Potomac Shore Lands by siding with the king.’ - President George Washington
