My 2nd great grandmother was Ellen McSorley. She came from County Tyrone and settled in Newark,NJ before 1830. I have not found her birthplace in Ireland or determined how she fits in to the McSorleys there. But I do know she had close relatives in the United States. I learned this by reading the church records of St. John's church, on microfilm, line-by-line. The reward for this was a small collection of Ellen's relatives and associates. Here are some of the McSorleys and their associates of Newark, NJ.

I extracted these entries using FHL microfilm no. 1398540. If you think you have a connection to one of these individuals, I'd be happy to exchange information.
