I am the great grandson of Henry J. Heyer. Henry was born in Germany, and served in the Kaiser's army prior to, or during WW1. He came to the U.S. (date unknown) and later married a Brigid Conlon. They probably lived in Westford, Massachusetts for awhile, and then moved to Lowell, Mass.They had a daughter (Mary R. Heyer) born in Westford,Mass., in 1884 - died 1965 in Mass. Henry died in the late 30's or early 40's here in the U.S.(don't have any dates). They also had a son named Benjamin.This is all I know about Henry Heyer and my grandmother (his daughter Mary R.).Please contact me if you are related, or have any family information that will help me in my research. Thanks!!!
