Hi, I did a little research and here is what I found. Alan Henry Courtman was a toolmaker born 20 Dec 1925 in Chelmsford, Essex, England died 3 November 1979 in Milwaukee, Wisconsin. He married Shirley Ann Willis on 5 September 1953 in England. They arrived in New York 13 Oct 1953. Shirley was born 14 August 1935 in London, England. The two did get divorced 16 November 1977 in Texas. They did have two daughters, Diane Marguarite born July 8, 1954 and Hilary Lynn Sept 15, 1958. I found information for Hilary. She married Roger Dale Lay and have a couple of kids, Brittany and Phillip. I believe this is her address, 4 Mountain Birch, Littleton, Colorado, USA 80127. This may or may not be the correct phone numbers, 1 303 972 9656 or 1 303 948 8926. I hope this leads you to your relatives! Good luck!
