A Mary Flansburgh, b. date unkown to me, was the eldest child of Peter Flansburgh of Jefferson Co. NY (b. Albany Co. 1800) by his first wife. After the death of his second wife in 1862, Peter moved to Kenosha WI where he eventually died. Don't know if this is the line you have in mind, Jackie, but Kenosha suggests that it may be. If you will email me with any further clues you may have about Mary and your Flansburghs, I will try to help you. Regards from a Jeff Co. Flansburgh descendant, Tony Sylvester Kitty Hawk, NC
