JC - Going to the historical society later this week, but found some info in Joanna Izer's obit. She died in Iron Springs, PA & was born & raised in Freedom township, Adams County, PA. An article from the Gettysburg Times dated December 24, 1937 is titled: Backgrounds of Adams County. It focuses on Fairfield & mentions Joanna (Lynn) Izer being the daughter of Jacob & Catherine (Harper) Lynn. It states "according the the family records the father of Jacob Lynn was Michial Lynn, but that is as far as our knowledge goes". I don't know if the spelling of Jacob's father is a typo or if that's the actual spelling. Will update you if I learn something new.
