I am trying to locate a Joan Clarkson formerly of Bonhill Dumbartonshire Scotland. She and her 3 sisters- Catherine, Irene and Isabel and mother Mary left 21 December 1956 from Prestwick Scotland to immigrate to the USA, arriving 22 December in NY. I have no further definitive leads, she may have married in 1960 a Norman Willis in California but I am unsure. I am trying to find her for my mother in law who was good friends with Joan when they were in school together however they both left scotland at the same time and consequently lost touch. It would be lovely to help Jose (Ryan nee Hayward) find her old friend. If anyone has contact details for joan or a lead I would be most grateful.
