It may be possible to confirm family relationships with Elizabeth 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 Elizabeth:
Ledbetter-921 and Ledbetter-318 appear to represent the same person because: Same name, same birth year, same birthplace, same parents, same husband. These two profiles are duplicates and the original merge proposal should not have been rejected.
Ledbetter-436 and Ledbetter-318 appear to represent the same person because: These appear to be same person, although spouse requires clarification, and with same profile manager, that should be possible.
Ledbetter-318 and Ledbetter-662 appear to represent the same person because: The parents are the same. While the birthdates are different, neither profile has sources to prove the birthdate. I would just mark the profile as undetermined which birthdate is correct.
