I'm trying to find out more information about my father's grandparents and aunt. Harry Wendel McGrath (b. 1887 Nova Scotia who also went by the name Harry William McGrath) and Dorothy Colbran were married in Brighton, England in 1918 before moving to Canada and having their first child Harry Colbran McGrath (b.21 October 1920) in St. Johns, New Brunswick. The family moved to Massachusetts where a second son, Ronald George McGrath was born on 28 February 1925 in Lynn, MA. The couple decided to adopt a daughter, Patricia Stone (b. 1937 in Lynn, MA) who eventually took on the family name and was known as Patsey McGrath. Harry and Dorothy moved to Galt, Ontario sometime between 1951 and 1953. According to family members, it is believed that Harry passed away on 19 May 1973 in Cambridge, Waterloo Co., Ontario and Dorothy passed away in January 1978 in the same location. Patricia also ended up moving to Ontario with her husband, Donald Cunningham. They had a son, Donald Cunningham Jr. who according to family records, died at age 21 years on 10 September 1978 in Waterloo Co., Ontario.
I am trying to find out: (1) The location of the graves of Harry, Dorothy and Donald Jr. (2) What became of Donald Sr. and Patsey (3) If they have passed away, where are they buried? (4) Did Donald Sr. and Patsey have any surviving children? (5) Details of Patsey and Donald's marriage - was it in Massachusetts or Ontario?
If anyone is able to assist, it would be greatly appreciated.
