My grandfather was Robert Alexander Fishwick born around 1910 and died 1984.He had a brother Richard, was one of 13 children and was from Bury, so would probably be part of the family.He emigrated to Australia in 1965 with his wife Elizabeth. Prior to that he had a truck and taxi in Bury for some years.
My Father is Sam Fishwick, born 18/10/1933 in Bury.
If it is the same Richard Fishwick, my grandad always spoke very highly of him as a 'favourite' brother. There was little contact between siblings as far as I know.
