I'm looking for any information on the family of James J. Brown and his wife Mary who lived in D.C. in the 1880s. Before that they lived in Massachusetts and Pennsylvania. I believe Mary was an Irish immigrant, but James was born in the U.S. James' father was from Ireland and his mother was from New Brunswick. They would have been born around 1840. They had four sons: William H., James F., John, and Thomas. I'd appreciate any help anyone can give me!
