My 2nd great grandfather Michael J Gallagher was born in Errris in March 1836. He married Mary Deane in 1859. Their children were James Francis, 2 April 1862, Michael Laurence 14 May 1864, Patrick 3 July 1866, Margaret 1 February 1871. I have no specific information about 2 other sons Dennis and Owen. At least Michael, Mary, James (my great grandfather), Margaret,and Michael Laurence emigrated to the US sometime between 1872 and 1875. I have no death information for Patrick.
If anyone is able to help with further information, I would appreciate it.
I searched the subscription site Roots Ireland and found baptismal records for James, Michael and Margaret. There was also a baptismal record for an Unknown child in 1866 who was likely Patrick. I also found a record for a Dominick born August 15 1868 and a Martin baptized December 29 1872. I did not find records for Denis and Owen.
