I have a book compiled by Mrs. Mabel Libby Booker called the History and Genealogy of Chester, Maine. It is dedicated to the pioneers of Chester, Maine and their descendants.It has collected information on the Chesleys, mostly where they are connected, using the numbering system that goes out to abt 7 generations.There are few sources for the items individually and there are about 9 pages of Chesleys. There are some dates and places given. There are a few family stories included. This might help someone find a clue for research, I found some mistakes in the Beatham family section, but it was worth reading.
