I have been given a number of documents and photographs relating to a Henderson couple who immigrated to Canada in 1922, leaving behind a number of relatives in Scotland. There are no living descendants of the 1922 immigrants. I would like to find cousins who would be interested in having the materials which I am holding. The immigrant couple were William J. Henderson born 8 December 1889, died 8 February 1974 and his wife born Agnes Winning Ross on 5 August 1896, died 31 August 1982. The both died in Vancouver, British Columbia. I have the names of both their parents and 1944 & 1945 letters from a Dick Henderson, apparently a nephew, mentioning a number of family members. I have no experience doing Scottish family history research and am at a loss as to how to proceed.
