I tried to post under your post "Looking for the Brenton Methodist Church" but for some reason it is not showing so I'll try again.
The Brenton Methodist Church is on the "Brenton Road" which is a dirt road between East and West Brenton. I can't tell you the Civic number but may be able to find it if necessary. The Brenton Cemetery is on the west side of the Methodist Church.
There is no Baptist Church in Brenton. I'm not sure what the NSMR would be calling the Brenton Baptist Church. The Baptist people could have used the Methodist Church for their weddings? There is a Baptist Church in Lake George and a Free Christian Baptist in Deerfield.
I should tell you that there is a private Crosby cemetery in West Benton on the west side of the Lake George Road. There 4 or 5 stones. They are the family of Sylvester Crosby who lived almost directly across the road.
Please ask questions if this is not clear. And I hope it posts.
