Perhaps a long shot, but here's what I have and maybe there's a connection:
Thomas Docherty (1848-1895) married Janet Strachan (aka Jenette, Jeanette)on Feb. 21, 1872 at Kilwinning, Scotland. Both from Ayr, Scotland.Janet was born March 30,1850 to Robert and Susan Strachan and died in Alabama on April 2, 1929.Thomas & Janet Docherty had 8 children (to my knowledge), one of whom was named Robert.The first 7 were born in Scotland while the 8th was born in 1888 in Pratt City, Jefferson Co. AL where the family had moved (sometime after Oct. 1884 but before May 1888). This last child died at the age of 2-1/2.
Although I have no information to suggest that Janet/Jenette Docherty remarried, there's nothing in my records to say she didn't!Hope this information turns out to be helpful.
