I have been searching for my 4th great grandfather's birth, parents, ancestry for over 40 years, but he did apprentice to his future father-in-law when sometime after his birth in 1761 in Boston and before his service in the Rev War in 1776 from Lanesborough, Massachusetts.
He was also a Mason.
Would either Masonic records (if I can locate them) or Apprenticeship/Indenture records perhaps show where he was born or any other family members? Where would these be kept for a given town, such as Lanesborough?
