It may be possible to confirm family relationships with Sarah by comparing test results with other carriers of her mitochondrial DNA.
However, there are no known mtDNA test-takers in her direct maternal line.
It is likely that these autosomal DNA test-takers will share DNA with Sarah:
Cornell-2254 and Cornell-1627 appear to represent the same person because: I removed the impossible mother born 1638, so now this is the oldest maternal ancestor in this chain in need of a merge. Now no tree conflicts. Thanks!
