I am looking for the relatives of a Micheal Shea who was a twin brother to Cornelius Shea. His twin, Cornelius is my GG grandfather. Cornelius had sons Patrick 1834,Jeremiah 1839,John,daus Ellen 1844,& Mary 1836. All of Patrick's family immigrated to US. Michael married a Bridgit and had two sons Mathew b.1837 and Patrick. I am sure there were other children.I have almost completed the line for Michael's twin brother Cornelius but am having trouble locating information on Michael and his family.
