My line of Gowins/Gowin/Gowing is descended from Nathaniel (Martha Proctor's husband). I've just managed to piece it all together down to my grandfather from Uhrichsville, Ohio. I'm happy to share.
I'm related to Elizabeth's brother William whose father (John T. Gowin) died of disease in the Civil War.
