Help I'm desperate for ideas

[Mama1980]

Hi My grandad had a sister and brother that he never saw after his mother and father split, he stayed with his father the others their mother. He was born in 1911, his sister 1910 his brother 1914 so were talking a whole ago. He was especially close to his sister as children and he was always desperate to find out what happened to her. He died in 1992 but my grandmother is still alive and she really wants to find out. Problem is after the 1911 census she vanishes, I have tried the notice boards and every combination of her name I can think of. What can I do? Any ideas gratefully recieved

Have you checked birth and deaths n the area? Marriage? What about asking the cuhrches in the area where she lived?

I would contact your local family history centre and pay an archivist for some help (assuming you have done all the standard document searches yourself).
