It may be possible to confirm family relationships with Jannetje Stevens 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 Jannetje Stevens:
Van voorhees-6 and Van Voorhees-35 appear to represent the same person because: Van voorhees-6 and other duplicate profiles for Jannetje, wife of Jan Martense Schenck, include enough information to confirm they were for the same person as Van Voorhees-35, whose profile shows her second marriage, to Alexander Simpson. Van voorhees-6, although a lower number, has a lowercase "v" for voorhees, making Van Voorhees-35 the lowest-numbered, correctly spelled profile for Jannetje. Thanks! Liz
Van Voorhees-85 and Van Voorhees-35 appear to represent the same person because: Van Voorhees-85 was identified as a duplicate profile for Jannetje, wife of Jan Martense Schenck. The duplicate profiles included enough information to confirm they were for the same person as Van Voorhees-35, whose profile shows her second marriage, to Alexander Simpson. Van Voorhees-35 is the lowest-numbered profile with the correct styling (two words, cap Voorhees). Thanks! Liz
