My maternal grandfather died in approx 1962. He lived in Slough, England but apparently came from Latvia. He had changed his name to Ralph Johnson but we have little other information. I believe his family name was Rogier or something like that. He left his homeland at the age of 14. ( Riga, Latvia). Family history says he had 2 brothers and a sister. Brothers possibly in the Cavalry. Talented artists and musicians. Any leads would be gratefully accepted.
