Henry Latour b. 1847 Canada d. 1927 buried Williamstown NY.

Mary Greenwood Latour b. 1860 Canada d. 1888 buried Williamstown NY.

Looking for any info on their ancestors and children. They had two daughters that I know of, Mary Latour Congdon b. 1880, and Helene Latour Heaney b. 1876.

In the 1920 Census, Mary is divorced, living with her father Henry, whose name is appears as "Henry Turner", Amboy NY. According to census reports, Mary and Helene were born in NY, however I can't find a census of their parents.
I have a picture of Mary Latour Congdon, also pictures of Henry Latour and Mary Greenwood's headstones.

Any further info is much appreciated
