Shelley:
Welcome to Ireland Reaching Out!
Can you provide some approximate dates on the years of birth for your ancestors. Were all of these ancestors living in Ireland.?
I looked in the 1911 census for Richard Fitzgerald in Co.Kildare and did not see a likely record (there was an 18 year old Richard whose parents were Patrick and Elizabeth). I did not find a civil death record in 1942 for Richard except for a record down in the Clonmel area of Tipperary who did not appear to be your grandfather.
