O'Meara O'Mara Clan of Tipperary, Ireland.

This is my 4th great grand mother who came from Tipperary Ireland.  I am looking for information about her and my family before she came to America and married my ggggrandfather.  Here is what I know.
  Does anyone have information on her father, John O'Meara or her Mother Ellen McDonald.  I am wondering if I am part of an Irish clan in Tipperary.
