Everyso often when searching the 1920 census for African American home owners in the DC neighborhood of Truxton Circle, I get someone who isn’t a home owner. Ernest E. Brown, a printer, reported that he owned the house. When looking at the DC Recorder of Deeds records, it appears it was owned by Alvira A. Buck instead. She sold the property in 1925.
So this is a dead end.
Moving on.
