it has been some time since your post and you may have got this information already. I think this is your great grandmother and two children in Moyaliff (near Holycross)in the 1901 Irish census.http://www.census.nationalarchives.ie/pages/1901/Tipperary/M...
There is also a marriage reference for a Peter Cleary with a possible match for a Margaret Hogan in Thurles Registration district 1908 Quarter Jul Sep volume 3 page 440.
The marriage cert should show father's name for both bride and groom and you can get a cert by downloading an application from at www.groireland.ie
Hope this is of help
