It may be possible to confirm family relationships with Susannah 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 Susannah:
Hughes-7838 and Hughes-958 appear to represent the same person because: I think that these are probably duplicates; however, there are some problems with Hughes-958. I'm not sure that the other two husbands that are connected to her are correct, and she is also not mentioned in Thomas Scruggs' will despite the fact that she allegedly died after he did.
