Alison, We too have had good luck doing research in Warren Co., the library, the court house and the Historical Society. It really got us going on my husband's family. It seems your ancestors took the same path as the Tobeys. From Bristol Co. MA to Dutchess Co., NY to Windham Co. VT to Chautauqua Co. NY and Warren Co. PA. One of my husband's gggrandfather's sisters married Thompson Rawson Feb. 18, 1829. Wonder if we have a connection. We have been to Warren 3 times in the last 7-8 years and to Jamestown and Frewsburg twice. Several of his ancestors who died in Sugar Grove Twp. in Warren Co. were buried in Maple Grove Cemetery in Frewsburg NY. The city hall in Frewsburg has a book with burials listed in the cemetery. Genealogists must be infinitely patient. Jean Tobey
