I have a very old, but similar post on this person existing, but it is dead.
My great grandmother was Frances Fitzpatrick, daughter of Royal Irish Constable William Fitzpatrick and Bridget McCarthy. She is one of 16 children and she was born in Fethard in County Tipperary in 1895.
She had an illegitimate son in 1927 named Joseph Francis Fitzpatrick. The name of his father is not registered on the birth certificate. Joseph was born in Cashel in County Tipperary
After 1927, I do not know where she went, if she remarried, had any more children and when and where she died
Any help would be appreciated, but I am rather pessimistic at the moment, irish records are notorious and no one knows about Frances in the family
