Posted on: Tioga Co. NY Queries Reply Here: http://cgi.rootsweb.com/~genbbs/genbbs.cgi/USA/NY/Tioga/10263 Surname: DUFF ------------------------- I am trying to determine the relationship between Sarah DUFF of Tioga Centre and the BURNS or YEOMAN families of Delaware Co., NY. In a letter written in Tioga Centre in 1866 to Jane Yeoman/Burns she addresses her as "Dear Aunt" and refers to the Alexander Burns children as her "cousins". The letter sounds like she may have been the wife or sister of "Andrew". Does anyone know who Andrew DUFF married? Or how "Sarah DUFF" is related to the families in Delaware county?
