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.

Gr-gr-gr-grandpa Philip Johnson with Margaret Estelle Whitford
Notes
We have a nice five-generation picture which includes Philip in 1913, when he was ninety. There is another one taken around the same time in which he has Margaret Estelle Whitford on his lap. The story is that he was blind in his old age.
Philip's gravestone has been photographed. According to the RI Cemetery Database, the Maple Root Cemetery "is a very old cemetery containing many inscribed field stones for the earliest settlers in this area. Records at Town Hall indicate that the first lot in the newer section was sold to Philip Johnson on 7 Nov 1893." I would guess that this was my 3xGreat-grandfather Johnson, or else his son Philip R. Johnson.
In the 1860 Federal Census, Philip & Triphina H. Johnson are living in Coventry, RI. In the home are Hearty P. 10, Philip R. 9, and Triphina 5, as well as Persilla Johnson, 74, Philip's mother.
By 1870 Philip has remarried, and he and Phebe are at Coventry with three children in the household: Ednah P. 9, Patience J. 6, and Zilpha W. 1.
In 1880 they are still at Coventry, and two daughters are with them: Orvilla P. 24 and Zilpha W. 11. Orvilla is Phebe's daughter from her previous marriage to Isaac Paine.
