I have been researching a Bridget Colgan born circa 1846/7 Ireland. on Family Search.
I have found your Bridget Doyle who married Mr Cornelius COLGAN a bit of an enigma. She is 19 years old when she gives birth to her daughter Matilda and yet she has no more children even though she lives until 1924 and Cornelius lives until 1907. Wouldn't you think that she would bear more children in the interim?
