I don't have any other information than what I posted. So it is possible there is a link to your Mary Ostrom. I don't know if David Waters Ostrom had brothers or sisters. My Ostrom's moved on to Orwell, Oswego Co, NY in 1850. In 1860 and 1870, they were in Vinland, Winnebago Co, Wisconsin according to census records. In 1900, David was 90 yrs. old and living in Stokes, Roseau Co, Minnesota. They did settle on land in Strome, Alberta, Canada around 1903, also.
