This website is part of an effort I am undertaking to compile family trees for all O'Donnells in Southern Tipperary, whether related to me or not. The sparsity of information for family history prior to 1850 means that it is often difficult to follow one's own ancestors backwards. Compiling a list of O'Donnells upwards makes it easier for a family researcher to find exactly where their ancestor might fit in.

Families are organised in terms of Civil Parishes. For a full list of the Civil Parishes in Tipperary, and the townlands they contain, see the list here
