Research Notes:
DNA [1]
[1] The family tree of a person who has a DNA match to a sibling of Janet suggests a lineage to Victor François Samuel Fivat who is a sibling of Janet's ancestor Louise Lydia Fivat, child of Jaques Rodolph Fivat and Françoise Pidoux. The DNA match suggests a relationship of 5th to 8th cousins. Our genealogy research and the tree of the cousin suggest a relationship of 7th cousins, with descent: Isabelle Fivat, Lydie Detrey, "Phillip" (Philippe Isaac Marc Francois) Dutoit, Francis Emile Dutoit, Eugene Ernest Dutoit, Frances Elizabeth Dutoit, [Link].
