Thanks for checking out the Brownellers.The Browneller settlement in Fayette Co. is the first place I investigated. It was next to the Van Meters which makes me wonder if Sarah came from Fayette Co. PA.
Sarah Browneller Terman was born in 1829.The Sarah Browneller, b.1831 Fayette Co. PA, married Stockdale Snyder, if I recall correctly, in 1849/50 -"married within the year"-in the census.
The Fayette Co. Brownellers seem to have been the same family as the Brownellersfrom S.E. PA which is where all indications point to being the area where Sarah (Browneller) Terman's family came from.
