My maternal grandfather is Aurthur M. Chamberlin. He is about to pass away. We have a book written by Maria Louise Barrett chamberlin. I believe she was his grandmother. The name of the book is Looking Back from Eighty-Five. Her sons were Henry Barret and Arthur Marshall. My grandfather must be Henry's son because she dedicates the book to Arthur "who left us before the journey was ended. We are looking for info for an obituary for grandpa.
