Yes lizdb, see stayed in Ackworth and died in '71 registered by her daughter. Their mother also died in the same house in 1945, my thoughts are Sydney left when his mother died.
This is quite a complicated story but the bones are he left Shropshire around 1943 and we know for definite he went to live with a sister in Ackworth, his mother died in 1945 and as far as we know there was no further contact with relatives in Shropshire after that.
He had 22 brothers and sisters and all but 3 brothers moved up to Ackworth and the surrounding areas so Im hoping that any of their descendants may know what happened to him.
