Richard Paterson WEIR b. 4 Jan 1912 in Edinburgh, Scotland and his brother James McDonald Weir b. 3 Jun 1915 in Edinburgh, Scotland. Believe emigrated to Montreal with mother Elisabeth Fraser McDonald/WEIR b. 8 Dec 1887. Also believe she re-married someone with surname of Martin, after her husband James Weir b. 5 Oct 1878, was killed in WW1 on 5 Sep 1917 in France. So could now be Elisabeth Martin. Sons may have taken Martin as surname?? James (1878) was my Grandfather's brother, and his son Richard Paterson Weir (1912) had identical name to my father and was his cousin.
Would love to hear from anyone with more details of this family.
