Samuel and Letty Halley were originally from Virginia. They settled in Mercerville, Gallia County, Ohio, where they were married in 1826. The family's last name at that time was Holley or Holly, later changed to Halley. Samuel was one of the first trustees of Guyan Township. If yo think that there may be any connection, I would love to hear from you! My e-mail is Bobbybbc@yahoo.com
