Yes.
I know...but strange 11 July 1924. ....11 July 1923.
Strange other folk have Thos William as Joseph's father..... that same Joseph marrying Ivy Stacey.
And quote the same 1939 census.
That military number is Thomas William Clarke,s.
I had a marriage cert where the father,s name was rubbish...it quite throughme.I knew her father,s and mother's names.
People lie on marriage certs !
The military cert the op has sent for should solve the mystery.
Still Joseph,s military record should have all info on it when it comes.
Might be worth following Patrick Clarke born Carrick on Sur Tipperary a d see what his father,s name is.
