Victoria Robertshaw (b. ca 1842) - the eldest child of William and Mary - and Alex Bosley (b. ca 1840) were married 16 April 1860 in East Gwillimbury, Ontario, Canada. They had two children - both daughters.
The first child was born
10 August 1860 in New Market, Ontario, and they named her Mary Elizabeth. Their second daughter, Lydia Ann (who went by the name Anna), was born in Ontario around 1864.
Mary married a man by the name of Charles Wilson and the two had three daughters. At this time, I only know the name of one of their daughters, Victoria. The other two I only know by their married surnames of Seely and Wolf.
Victoria Wilson married a man named James A. Munro in Port Huron, Michigan on 25 June 1896. As far as I know, Victoria and James did not have children. More research is to be done on any possible descendents.
Victoria and Alex’s other daughter, Lydia Ann  (who I shall refer to from this point on as ANNA, as that was what she was known as), married a man named George Sweet. Anna and George had two children, Bessie (b. 18 March 1880 in Canada)
and Elmyra (b. 11 Dec 1884).
Bessie, who worked as a dressmaker, married Paul Lewanski (b. ca 1887) on
5 December 1907 in Port Huron, Mi. They had one child that I know of for sure - a daughter named Pauline, who was born in 1909. Pauline married someone by the name of Watson.
They may possibly have had one son, also, named Carl. More research is to be done on this.
Elmyra married Donald McKay in Port Huron and they had two daughters - Ethel (b. ca 1904) and Thelma (b. ca 1908).
