I have limited information on Dora Pollock in my family tree--I'm related to her husband, Henry Hardwick.
I have Dora born in Wisconsin around 1861, the daughter of George and Sylvie Pollock, who were born in NY. Dora married Henry Hardwick in 1876 in Oconto County, Wisconsin. Their daughter Irene married John P. Carlson in 1914 and they lived for a time in Kipling (Brampton Twp.) as well as in Escanaba.
