Hi!Just saw your message today.I think I may have found some of the information you are looking for in the Waldo Lincoln books. Here's what I found:
Edward Waldo, b. May 14, 1742; d. Jan 22, 1829--married Jerusha Thompson Nov. 17, 1763.
Elijah Waldo (son of Edward & Jerusha),b. April 12, 1764; d. 1832 in Langdon, N.H., married: (1) Betsy Angier (b. Sept.1, 1768; d. Feb. 26, 1807. (2) Betsy (Cobb) Wellington
Samuel (son of Elijah Waldo and Betsy Angier Waldo), b. Jan. 24, 1794; d. May 28, 1875 at Crescent, IA; married Orpha Walker.Children of Samuel and Orpha were: Sarah Elizabeth Maria Asa Perry Samuel Franklin Rosamond Walker Elijah Dana James Noble
One interesting fact I found about Samuel was that he became a convert to the Mormons and went west to join them, but withdrew from the group, along with others, because they didn't believe in polygamy.They organized their own branch of the Mormon church known later as "The Reorganized Church of Jesus Christ of Latter Day Saints" He was ordained as an Elder in 1860.
I hope this helps.I'd be happy to help you with anything else, if I can.
