Did this change over time? I suspect there are fewer at each meeting now. I am not sure they even still have meetings. At one time half of Portsmouth Rhode Island were Quakers. It makes it harder, but You may have to take time into account as meetings change.
The dates from the first book list 1737, 1743, 1751
Are the Rhode Island names Gurneyite, FUM, Wilburite referring to splits into factions? This would be time dependent too.
Joseph John Gurney and John Wilbur had different views. I have found dates in the mid-1800s. "Joseph John Gurney (1788–1847), the most charismatic and most influential of the English Orthodox Friends to visit America (1837–40), which brought these differences to a head and sparked the first Wilburite separation, in New England Yearly Meeting in 1845. " "John Wilbur (1774-1856) was a lifelong Friend from Rhode Island..he published a book of letters to George Crosfield...protracted conflict with the leadership of New England Yearly Meeting...supporters organized a separate Yearly Meeting"
I found the profile for John Wilbore and adopted it. This might make sense as a Quaker project profile.
I found the profile for Joseph John Gurney (1788–1847) and added a Quaker sticker.
