This information was found in the Bristol town records, p. 43 of the old marriage listings. I have a photocopy.
It is also listed in James N. Arnold's Index of Vital Records for Bristol (a tan library-bound book).
In the front of my grandmother's old Bible there is this notation, written in her handwriting: "Lest I forget, I must write down the Chafee family motto -- 'As we journey through life, let us live by the way.' It is above the large fireplace in the Chafee Hotel in Middletown Conn. made in the masonry."
