I accept there are no passenger lists (or so I think) for passengers from Sweden to London in 1946, but is there any way I can trace my grandad? He was born 1928 as Valdis Valdeman Krilovs, his father died very shortly after his birth. His mother remarried and he became Valdis or Waldis Swensson. He was born in a place beginning with 'V' in Sweden (that could be the village, town or district, no-one knows), came to London in 1946 and went back again a few years later. He returned to London c1951 for good, possibly changing his name from Swensson to Krilovs. He died 1981, having destroyed all his I.D. Naturalization records at Kew is a possibility, but wouldnt there be a 100 year secrecy ruling on them? I know he attended a boarding school in Stockholm but I dont speak Swedish and dont know if they'd give me records anyway, plus I couldnt translate them...even if I knew where the school is/was. His parents were Aleksander and Annette Krilovs, his father was a naval captain but all avenues have been explored there, and he's untraceable.
