Collverites -- A Quaker-like Religion

I have been doing some genealogy research on the Collvers. The name "Collver" or "Culver" means "dove" or "pigeon." It seems that the first Collvers who came to America were of the Puritan sort, arriving in 1634. Of interest to me (especially as a Lutheran pastor) is that some of my ancestors were involved with the Rogerenes (check them out in Wikipedia). Apparently the Collvers had their own version of it and lived on Schooley's Mountain, Morris Co., NJ. In any case, the book Pioneer Families of Northwestern New Jersey by William C. Armstrong describes the "Collverites."
