Unknown couple

Oldest images I have. Probably taken of portraits. Images are on glass (ambrotypes). Perhaps he is a minister-- what type? Is it Congregational? These are unidentified. His image is backed with another that appears to be a daguerotype. Farr; Alsobrook; Watkins; Baine; Mckiernan; Lyons

I have ancestors that came from Sudbury, VT. Allen S. Farr (b. 1833)was a Congregationalist and his parents, Lyman and Nancy Lyons Farr, lived in Brandon, Vermont. Lyman's father may have been Salmon Farr Sr., and Nancy may have a relative who was a Swinnnerton (Vermont minister?).
