Upon reading the Elder John Crandall descendants book, I notice Lyman Crandall m. Bridget.Lyman B. Crandall is my gg grandfather, b. 09 May 1838 in Berlin, N.Y.He moved to Hoosick Falls as a young child.Lyman married Bridget Welch 04 Nov. 1861.They had six children, one being John L. Crandall.John L. Crandall moved to Milford, MA and died there on 14 Mar. 1940.I do not know who the parents of Lyman B. are but I am interested in finding out. It seems that Lyman B. Crandall and Lyman Noble Crandall have been confused.
