Just to note:There is a birth of Christopher Fitzgerald , Croom Workhouse, with mother Eliza Fitzgerald.Birthdate is 12th December 1909. https://civilrecords.irishgenealogy.ie/churchrecords/images/birth_returns/births_1909/01587/1638555.pdf
It is only a possibility - could be just coincidence but worth noting just in case. I have looked for Fitzgerald/Carey marriages but can’t see anything.You gave a list of siblings for Christopher. Do you know if they stayed in Ireland?Is Dawes the married surname of Peggy?
I thought ‘Friars Walk’ sounded familiar .I saw this death last evening - 1944 John Carey, 67 yrs, married Labourer of 36 Friars Walk.informant son, Timothy of 34 Friars Walk.https://civilrecords.irishgenealogy.ie/churchrecords/images/deaths_returns/deaths_1944/04646/4235144.pdf
