This is pretty exciting to find someone related to Sarah Ann Cummings Sutherland White! Her younger sibling or half sibling David Cummings went with the Sutherlands and Cummin(g)s to Ontario where they stayed long enough for him to marry Martha Sutherland and have daughters Sarah Ann and Susannah Cummings, before returning to Lewiston, Niagara County in New York State. Eventually he went to Branch County Michigan and briefly to LaGrange County, Indiana in 1840 where he and brothers (or half-brothers) Major and William opened a store that didn't last, apparently, as he was back in Michigan by 1850.

I'm pretty confident these are relatives because Susannah Cummings had a daughter by her husband David Hartsough that she named Euretta.

Can't be a lot of other Eurettas out there!

David's son William Major Cummings was my great grandfather.
