Hi everyone,
My dad was adopted by George James Carroll (1928-1989) and his wife Kathleen (~1930-2020). George James had a sister, Olive (b.1930)
George James' parents are George Patrick Carroll (b.1895 or 1897 Stepney/North London) who married Eleanor Florence Casey (1902-1971) in 1927 in London. On the marriage certificate his father's name is given as Patrick Carroll. George Patrick also had a brother William Patrick Carroll (1897/1902-1977 born Islington/North London, died Fareham). George Patrick's birth date is 1897 on the marriage certificate, but 1895 on his war record and a birth certificate I found online. William Patrick's birth date is listed as 1902, but another record could match him as a William Patrick Carroll was also b.1897 in North London. He could have potentially had a sister Sylvia (b.1901) however, the 1939 England and Wales Register which lists George James and Olive living in Somerset with "Sylvia Carroll", has been struck through and replaced with the details of Eleanor Florence, their mother, instead.
I can't find any sign of George Patrick and William Patrick with their father Patrick together on the 1901 or 1911 census via Ancestry, with or without including Sylvia. I've ran searches using barebones details like only first names, initials, no initials, even just searching for George and William together with no father's name, and no combination matching them has ever come up. I'm not sure if they were out of the country, their father had a different name, but if William Patrick was born 1902, they would had to have returned to England just for his birth, then left again, before returning after WW1. If he was born 1897 however, they could have left for a longer period and only returned after WW1.
If anyone can help crack this mystery I'd be very grateful!
