Diane, I'm a descendent of Isaac Longabaugh (although our family spelled it Longenbach) and Elizabeth Cole. I hadn't known the names of Isaac's siblings until I saw your message.Thanks for the info!!My family records say that Jacob settled in Fairfield, OH near the present town of Lancaster (which was a wilderness then). He was fond of hunting and spent several years among the native Americans and was well acquainted with their language. He served in the Ohio Militia during the War of 1812-1814, acted as a scout, and took part in several battles. After the war, he took his family and settled in Pickaway County, OH where he later died. Just a little trivia!
