I really can't vouch 100% for them but I can recite several sources I used all agreeing with this reading of the family. You may have others who can evaluate these sources better than I can. I did my research at the Connecticut Historical Society during genealogical vacations in 1967 and 1968 etc. I also visited the State Library, and this was part of a longer term project--I spent more time in Albany NY, also New York City and other smaller venues. I was covering my whole family spectrum, especially the Daytons, Barnes, Day, Judd, and other inlaws in Connecticut. In the stacks of CHS there were 4 box/ envelope items on the family of Robert Day. 1) file box DAY; 2 envelope Day camp collections; 3 Day Genealogy by Homer W Brainard; 4 envelope entitled Day, Dayton, Devotion, Deane by Harriet L Standish 1961 gift of Miss Mary A Northrup of Rochester, NY. Separately I found a stack file for the Butler Family: Richard Butler (deacon of 1st church Hartford) Immigrant ancestor of the Wethersfield Family came to Boston from Braintree Essex Co England 1632. First settler Cambridge Mass., then joined Thomas Hooker in settlement of Hartford. 1634-35 his elder brother William was in the company. Richard m 1 ??? m 2 Elizabeth Bigelow d Sep 11, 1691, Deacon Richard d Aug 6, 1684 in Hartford. Children by first wife: Thomas;Samuel;Nathaniel Children by 2nd wife: Joseph;Daniel;Mary;Elizabeth;Hannah Thomas bc 1637 at Hartford, m Sarah Stone dau of Rev Samuel. Had 4 sons and 8 or 9 daughters. The fifth child (not named here) m John Day of Hartford. I added note: Days call her Sarah. This goes on several pages of this family, but thought it might support our research. The Several Day files all agree John married Sarah Butler. I also found an envelope on Wilson - "Wilson Family Notes by L.B. Barbour," covering the fact that Robert Wilson married the daughter of Deacon Edward Stebbins , sister of Editha Stebbins Day.,dau was either Hannah or Elizabeth, and she m 2 Thomas Caldwell. Robert and Elizabeth/Hannah had John, m Lydia Cole, dau Hannah Wilson m Thomas DAY, whose dau Hannah m Thomas Barnes, my line.
