I have some information about Eli Buttrick and Sarah Parker for you!I am a 6th great grandson living in Lake County Illinois. Eli Buttrick married Sarah Parker, 29 Sept. 1791 in Concord, MA.They had a total of 11 children that I know of.Their eldest, Susannah Wood Buttrick, is the line in which I carry through.His most notable son, Hiram, built the first mill in Antioch, Illinois back in 1841 as they were one of the first families to settle there. (Google "Hiram Buttrick") lots of stuff on him... Eli died in Antioch 18 April 1843 and is buried next to Sarah who died 21 Dec. 1850. Hiram traveled with another relative of mine from Antioch in 1850 to California during the gold rush.I have copies of correspondence naming him there, and wishing his family well.... I am not too tech savy, but I did make it out to the cemetery in Antioch this past summer and took pictures of Eli and Sarah's head stones, which are in remarkably good shape. I hope this info. helps you out!Feel free to email me with any questions.
