The subject couple are my 2nd-great-grandparents. I would be most grateful for details about them from the time of their birth when they immigrated to America. Here is a timeline of everything I have about them during that period:

1829 Feb - John McDemott born in Galway
1831 Apr - Julia Holins born in Galway
1852 (abt) - marriage
1854 Sep - daughter Mary (my great-grandmother) born in England
1855 - Arrival to US
1856 Nov 26 - son John J McDermott b. in Wisconsin

Thanks for any clues.

Regards,
Daniel
