I am really struggling to find information on my great grandmother Julia and her son Thomas. Her surname is suspect either Clarke or Jacques. Therefore I am attacking it via my grandfather and his brother. Unfortunately Julia was a bit of a girl and all three of her children were illegitimate. On my grandfathers birth certificate it has her as Julia Clarke and no father and I can find both her and my grandfathers brothers all living in the same house in 1911. My grandfather was head of household. His brother Thomas Clarke, I have his death certificate and his marriage certificate. His birth date is 3rd Feb 1901 but try as I might I cannot find any details on any of the sites I look in for a birth registry therefore cannot order a birth certificate. I have moved the date a couple of years either side. Can anyone help as I've reached a roadblock?
