I have a copy of a sheet from a book 'Historic Graves of the District of Columbia" which has information on the Addison family: "Much of the local tradition of the past is linked with the name of Addison and with the old family estates of Barnaby, Oxen Hill and Gisborough.At Oxen Hill is the family vault and graveyard where dead of several generations respos.Col. John Addison died in England in 1706, and probably the first to be laid in the vault was Thomas, his only son and heir, with the latter's wives, Elizabeth Tasker and Eleanor Smith.The third generation is represented by John, Thomas and Anthony, all of whom were born to Thomas by his second marriage; also, possibly, John's wife, Susannah Wilkinson; then comes John's son Thomas, who married Rebecca Dulany, and some of their children and grandchildren.This brings us down to the Rev. Walter Dulany Addison, who was born at Annapolis, January 1, 1769, and died January 31, 1848.He is buried in the adjoining graveyard by the side of his first wife, Elizabeth Dulany Hesselius.She died 31 July 1808, at the age of 33."(This article continues on the next page, which I did not copy.)
I believe I am a descendant of William Hutchinson, who was involved in land transactions with Col. Addison in the late 1600s in Prince George's Co., MD.
