Hitting a brick wall ????

[lorraine76]

Is it possible to find illegitimate children's fathers? Ive been trying to search my great great grandfather David Black born 1887 in gatehouse on fleet. On his his birth certificate it states his mother as Mary black and verifies he was illegitimate. From there it disappears until he marry my great great nan Esther attridge. Id love to know did Mary keep him , was he raised by his real dad ect. I know he was in the 2nd life guards.

I have his war records it states mother Mary address unknown and I'm pretty sure it says older brother George??

So any ideas on how or if I can move forward??
