Well, it's a strange little search, but seeing as you asked...
My gggrandmother, at some time between her arrival in Canada in 1905 and her death in 1928, was the model for an oil painting that used to hang in the Art Gallery of Hamilton in the 1930s. The painting was entitled "The Pioneer Woman". My mother, when she was in her teens, used to go 'visit' the painting when the family was downtown doing errands. I've contacted the current curator of the gallery, and she's been unable to track the painting down.
I have methodically been going through the artists active in Hamilton at the time, and there are two likely suspects, Hortense and Marion Mattice, sisters who later became reasonably well-known Canadian artists. In the 1921, Marion would be caring for her widowed mother, Sarah Louise Crompton Mattice, and Hortense, having married John Sloan Gordon in 1920, will be, one would presume, at his address.
I am trying to see if these two artists are living anywhere close to Corktown, the area my family lived and worked in. So, in short, I'm looking in the 1921 for the addresses of:
Sarah Mattice, b. c. 1853
Marion Mattice, born 1878
and
Hortence Mattice Gordon, b. 1886.
Any and all info received with fawning gratitude.
