It may be possible to confirm family relationships with Jacob by comparing test results with other carriers of his Y-chromosome or his mother's mitochondrial DNA.

Konder-5 and Conder-45 appear to represent the same person because: These are duplicate profiles. Parents are currently in a proposed merge, and should be merged first. Conder is most common spelling found in US records.
