Hello,
Just for clarification - Timothy Clifford marries Elizabeth Madden in 1943
https://civilrecords.irishgenealogy.ie/churchrecords/images/marriage_returns/marriages_1943/08782/5174366.pdfYou say he emigrated to Birmingham and died aged 61 yrs - was that in Birmingham?
There is a death in 1976, Birmingham
Timothy Matthew Clifford 61 yrs date of birth 11th September 1914
There are electoral registers 1955 - 1965
Grosmont Ave Birmingham
Timothy and Elizabeth Clifford
There is a Madden couple there for some of the years so it looks favourable.
There is no birth with that exact date but there are these
https://www.rootschat.com/links/01rot/1914 - parents Timothy and Elizabeth (Sullivan)
There is a death for this child based on the residence Caherina.
1918 - parents John and Bridget
5th April 1918 parents Timothy and Lizzie Sullivan so this makes it more likely but caution because of the date of birth.
Is this what you have so far?
