My mother, Joan Mary Laslett (nee Miels) was your grandfather's (Ian Garvie) cousin. Her mother was Roy Gordon Garvie's sister (Mary Charlotte Garvie). I was in touch with Duncan Garvie, one of Ian's sons, but have misplaced his address/email etc. I met your great grandmother, Win, and your grandmother, Mary, many years ago, in the 1960's in NZ. If you have Duncan's contact details I would love to re-connect with him.
best wishes ... Suzanne Laslett (email:firstname.lastname@example.org
