Hello again
At last I have deciphered my mother in law's mother's maiden name to be Kate KILNEENEY; it may also be spelt KILKENNY. Margaret MULVIHILL born 16 February 1924 (died 19 August 1971) was born at Derryhippo, Roscommon, to John MULVIHILL and Kate KILNEENEY. John was a farmer and he and Kate also had daughters, Bridget, Ellen (Nelly), Ann (Nancy) and Kate. Lots of cousins there somewhere! I am afraid that's all we know so if anyone is also researching this family you are more than welcome to join in.
Regards
Janet
