I may have some information for you.David Sawtelle who married Rebecca Fiske was the son of Henry Sawtelle and Sarah Harrington.I have different dates for them.Henry and Rebecca had at least 3 other sons:1 Richard (1851-1838) who married Sarah Grout; 2 Henry (1745-1782) who married Jerusha Hudson; and 3 Joseph (1746-).Richard and Sarah had 5 sons: 1 Joseph (1777-)who married Sabra Nickerson.They had a son Joseph (1795-); 2 Elijah (1779-); 3 Richard (1781-) who married Lucy Peters; 4 Henry (1790-1834) who married Rebecca Farnsworth and they had four sons (Henry, Joseph, Lysander and Benjamin); 5 Eli (1796-1802).
Henry (who married Jerusha Hudson) had 4 sons:Henry Tertius, Levi, Rufus and Thomas. They also had 2 daughters whose names I don't know. Henry, Jerusha and five of their children died in Vermont when their cabin caught on fire in 1782.Only Levi survived. He grew up and married but I don't have that information at my fingertips right now.
Henry (Sr.) who married Sarah Harrington was the son of Richard (1689-1760) and Abigail Whitney.Richard was the son of Enoch (1656-1741)and Susanna Randall.Enoch was the son of Richard who came from Somerset, England in the 1630's and settled in Watertown, MA.His wife was Elizabeth.There are 2 generations before Richard.
Back to David and Rebecca Fiske.They had the following sons (maybe more): 1. Amos (1809-1851) who married Elizabeth Jackson and they had a son David Warren (1838-1861); 2 David (1797-1841); 3 Aaron (1793-1859) who married Lucy Davis and they had at least 2 other sons (Aaron William Richardson born 1828 in Jaffrey and Warren born 1832, died 1890 who married Christina Eveleth and had a son Oren born 1860, died 1928); 4 Warren (1800-) and 5 Henry (1802-).
I hope this helps.If you are descended from Aaron and Lucy then it appears that you are descended from Richard.I am descended from Richard through his son Zachariah (Enoch's brother) and so I guess we are very distant cousins.If I can give you any more information let me know. Gary Sawtelle
