1. The Mnntgormery Monument in Bel Air mentions two sons: John H. Montgomery and James N. Montgomery. Perhaps, the middle initial "H" in John H. stands for "Harris" and the middle initial "N" in James N. stands for "NIcholson". If so, this would suggest that John H. Montgomery was the son of his first wife Mary Harris and that James N. Montgomery was the son of his second wife, Maria Nicholson, and named in honor of Maria's fahter, Commodore James Nicholson.
Father: John MONTGOMERY b: 1764 in Carlisle, Pennsylvania
