My grandfather was John Wilson born circa 1886 in Glasgow, Scotland. His father was John Wilson Occupation Boiler Inspector and his mother was Isabella Dewar. My grandfather died in 1940 after emigrating with his English wife to Australia in 1922. He served in WW1. My mother told me that her father was related to a famous whiskey family but it was not until last night when I received a copy of his death certificate that I realised he may have been related to the Dewar's Whisky family. Do you have any information that may help me in my search. My maternal grandfather has been difficult to track since I did not have any information from my mother before her death 18 years ago.
