This is not answering your question but it should eliminate the Susan N. Ryckman Deforest who was born May 24 1824 & who died in Prairieville, Rice, Minnesota, on Aug 23 1890.
The latter Susan was born in Ohio and had been married to George L. Deforest b. NY. George and a couple of their children were buried in the same cemetery per Find a Grave. You can see census records for this family by searching on familysearch.org for Minnesota.
Even though Susan has been posted on Find a Grave as Susan Ryckman Deforest, I believe her maiden name was actually Nelson:
