Loughnane in Thurles Co. Tipperary

I am coming in late on this one as I just joined the site. I have been researching my John Loughmane family in Ireland for about 6 months. I know his mother is Mary Madden due to the death certificate lists this name. Keeping in mind that the Loughnane's and Loughmane's were noted different spellings. I am relations with John Loughmane who married Catherine Darcy from Terryglass Tipperary. I have most of their stuff for here in the USA but lacking some fill ins for Ireland. I am slowly working my way forward so any information that relates to this clan would be helpful. His sister Catherine married James Costello, Mary married John Sheehy and Margaret married Patrick Fogarty, brother Patrick Loughmane, James Loughmane and Michael Loughmane. The name in USA is John Laughman born 1808 Ireland lived in Ohio. I am still working on the brothers and their wifes. Thanks Sandy.
