I love your Abbott family web site, very well done. I know this was a lot of work. Your efforts have clarified a number of questions that I had about my ancestors. We are of the same lineage from at least William (b. 1657), and perhaps from a more recent generation. My grandfather, Charles Leroy Abbott (b. 1892, Littleton, NH) moved to Auburn, ME, then to Portland ME where my Dad was born (1918), finally to Newton MA, hence my birthplace in Newton (1949). My dad, Richard N. Sr. was a Pediatrician and practiced in Natick, MA, which is where I was raised. I lived in Maine for 6 years (Bowdoin '71, U. Maine '73), Somerville, MA for 4 years (Harvard, '77), in Canada for 2 years (Post. Doc., Dalhousie U.1977-1979), and up to the present in Boone, NC. <www.appstate.edu/~abbottrn>. I am an emeritus professor of geology. Most of my geological work has been in eastern Maine, Nova Scotia, western North Carolina, Dominican Republic, and Jamaica.
I have attached a copy of the my branch. My grandfather spoke of a couple of Myrons (one b.1841, another b.1803) and Moses (b. 1778). He also spoke of relatives from Newbury, VT. From Myron (b. 1803) it was pretty easy working backwards to William (b.1657) and George (b.1617). This was my effort to sort out the Rowley vs. Andover issue.
Take a look at the genealogy. One question, why the migration to NH and VT in the 1700's? The Littleton folks were farmers before migrating to ME. In Lewiston, they owned a dry-good store. My grandfather (Charles Leroy, b. 1892) was a musician/composer, then investor, a banker in Portland, and before he died, when I knew him, he was the first vice president of New England Merchants Bank in Boston. My grandfather (Charles Leroy) is cited in "The Heritage Encyclopedia of Band Music." He composed and arranged J. P. Sousa style marching band music. I guess this didn't work out too well, which would explain the move to banking. Nonetheless, pretty good for an 8th grade education.
I hope the attached genealogy adds to what you already know. I have more information on the recent generations.
