Looking for my great grandfather's history from Dublin

Hi im am looking into my great grandfather's history, all i know is his name is Francis Fitzgerald he was born 9th September 1913 and died 26th September 1979, he was married to my great grandmother Elizabeth Russell born 27th July 1915 and died 26th November 1999. i have no other information about these 2, i know some of their daughters names which is my nan Mary Jane, Carmel, Lily?, Kathleen and Frances, i dont know any of the sons that were born and i have no idea if Lily and Kathleen are still alive, the last I knew they were still in Dublin, where as my nan died in the UK in 2018, Carmel and Frances are still alive i believe but living in the uk.

I hope to hear from some of you soon.
