I also have a Warren in the same line.Zenas Lazell was President of the Mayflower Society...waay back.He was a descendant of Hopkins, Cooke and Doty...and he married Tabitha Warren.Sarah Lazell, daughter of Zenas married Robert Luce...they had 10 children.Sarah died in 1833 NY and Robert in 1838 in Bristol Indiana.My gggrandmother, Ellla Jane Luce was then adopted into the family of Josiah Flint Willard about the time Josiah's wife gave birth to Frances Willard, the famous sufferagette and President of the World Women's Christian Temperance Union.Frances Willard is the only woman represented in the Statuary Hall in the US Capitol Building.(were Ted Kennedy was stricken at the inaugural luncheon for Obama)
In any case, Ella Luce married Jasper Mallory and daughter Elizabeth married Susannah Bartlett great grandson, Henry Brown Daniels, son of Candace Sarah Emery whose grandmother was Susannah Bartlett...daughter of Josiah, son of Cpt Richard Bartlett, son of Richard Bartlett and Hannah Emery.
Susannah Bartlett's mother,Lydia hale, was daughter of Ezekiel Hale and Ruth Emery.Ezekiel Hale's grandfather was Ezekiel Northend, brother of Agnes who married John Emery...who was ancestor of all the Bartletts we have mentioned via granddaughterHannah Emery.
By the way, without going back through emails....was Lemuel born in Nova Scotia or had the family returned to the US.
Canadian records are pretty good....I have ancestors in Nova Scotia who then moved to ontario.They were UEL.
