Samuel was Hannah's father, wife of Samuel is Mary Brown.The Austin and Doty family moved to Butler Co. PA. 1814.Samuel was the local law enforcement there and you can find more info on that county web site. pagenweb, Venango co. They were in the south part of the county near Butler Co. Little Scrubgrass Creek. Some of the family likely stayed in PA. hope this helps tie in some pieces. check the 1800 census and read the county history on line.Samuel arrived about 1795 with the Scott group from Westmoreland Co Derry Twp.
