Please can anyone give me advice on the easiest way to trace what happened to my great grandfather William Gerrish. He was born in 1864 and his family lived in Melksham, Wiltshire. He was still alive in 1915 when he lived in Whitely, Melksham(stated on her death certificate) However as soon as my great grandmother died, my grandma moved out because he was apparently not a nice man. He did not attend my grandma's wedding, and she moved to Sheffield and had no further contact with him. He was a batchelor when he married my great grandmother, and as far as I know had no other children at that time. Therefore he had no real reason to stay in Wiltshire. I have searched the bmd indexes, but have come up with quite a few possibilities, but how do I know which is him? Is there a way I can trace his whereabouts after 1915? I have found it easier to trace backwards further with the help of censuses, however more recent relations seem more difficult to me. I know he was a plasterer and tiler- would he be likely to be registered in a trade directory? I would just like ideas on the quickest way to narrow the search down please?
