I’m looking for the descendents of Thomas Tierney (abt.1820-1869) from Ireland, who arrived in Baltimore in the early 1850’s. He was married to Margaret______, their children where Patrick, Ellen, Thomas, William, John, & Catherine. Patrick was a Baltimore policeman, and Thomas worked on the railroad in Baltimore. I am from the William side. William was born in 1860 and lived in Washington D.C.
