I have a photocopy of the original record from the official book of the Town of West Greenwich for 1851, p. 77. They were married on 25 Nov 1849 by Caleb Green, Minister of the Gospel, and the marriage was recorded by John James, Town Clerk, about a year and a half later. The minister, Elder Caleb Green(e) (elsewhere it is spelled with a final "e"), was married to Lucetta Nichols, daughter of Susanna Whitford and Ambrose Nichols.

Shippee reunion -- Mancer and Edna are in the middle; I think that's Gertie in the front right with the girl. Unfortunately I don't know who all the others are. Mancer and Edna had 7 children so some must be their other children and grandchildren.
