This man was arrested for larceny. According to the info on the other side of this card he was a painter. Looking in the city directory, a James T. Allen who was a painter who lived in Blagden Alley. The card also said he had brown hair and light blue eyes, and that he was a very light mulatto. Sure. Genes are funny things.
It also says he was born in Massachusetts. I can’t find other James T. Allens born in MA around the 1890s in DC. Plenty of James and James T Allens in DC, just not any from Massachusetts.
