Desperately looking for any info Re. Thomas Lett & Margaret Bolger,they had son Nicholas born 4th April 1867, who then went on to marry Mary Fitzpatrick,.
not sure what kind of details you have already on Thomas and Margaret.... details of extracted births for several of their children are included on FamilySearch :
Elizabeth Lett, 12 Mar 1864, Camolin & Cranford, Co. Wexford
Nicholas Lett, 04 Apr 1867, Gorey, Co. Wexford (district)
William Lett, 22 May 1872, Ferns, Co. Wexford
see :
Lett/Bolger birthslooks like Thomas and Margaret marriage before 1864 - so a search of parish records would be required if they were RC..
