Hello... There was a family member in my lineage with the last name Olds. His name was Reubin Olds and he was married to Almira Ferguson. They had a son Herbert Henry (b-1853) who was then adopted in (1857) by Sylvester Bemis Prentiss.
Sylvester was b-1817 in Chester and married (2nd) Louisa Williams, and died in Worthington Ma. Reubin Olds was a dairy farmer in Middlefield and is buried in the Pittsfield Cemetery. The ages would be about right for Reubin to have been a brother to George Olds (b-1833) in ma.
