I found something interesting, for Ebenezer Estabrooks on Ancestry.com a record/source for some of his information was "soldiers and sailors of the Rev. War. Comp. By secy. Of the commonwealth, Ms. Boston. 1896-1908. (17v.):5:389"
Was he a military man or something? I noticed that people have him as born in Massachusetts having moved to and died in New Brunswick.
