I haven't checked the registers, but transcripts suggest a child Bridget in 1863 (26 April), Pat in 1865 (16 January), John in 1866 (9 January), Ellen in 1868 (7 June), James in 1871 (1 October), Catherine in 1874 (23 January), and Edward in 1876 (28 May).
I was told that Thomas had siblings Margaret, Tessie, Eddie, Bill and Jimmy at least. No dates were given and I've looked all evening but haven't managed to unearth any you haven't listed.
