Robert Bell Sedgwick [Alfred Blair Sedgwick / Sophia Julia Bell
Henrietta A Rogers [Unknown Rogers / Henrietta Unknown1]
Note that Robert's age as given in the ship's manifest upon their arrival in the US does not agree with his correct age according to the birth records. However, in the 1900 census he also stated that he was born in 1849.
I saw a line at FamilySearch.org that shows Henrietta Rogers descended from "Thomas The Pilgrim ROGERS" of the Mayflower.
