I now know my g grandfather came from Galway but do not know when he sailed over to the US. or on what ship. and with who. but he did marry in Maryland in 1850 and made his way to green bay, wis and died her in 1890. Also need any info on a Catherine Sheehin, she was only 23 when she married peter in 1850, and he was like 50 years old........ And do not know Peter's parents but i bet it was Michael Tierney......... because that was Peter's first born son's name and that's how they usually did it.
