Hi everyone: I am new to this mailing list. I am trying to find my ancestors but have no idea where to start looking. All I know is that my ggg grandfather "William HARRIS" came from Ireland (listed on his Philadelphia, PA USA census forms). I am estimating the time to be between 1811 (the year I believe he was married) and 1830. I have been unsuccessful in find him or his wife "Mary" on any ship lists. Any help is greatly appreciated!!
