I have seen references to their marriage, but have never tried to follow up with any research effort.
I have found very little info on Fonner's before 1800 - unfortunately. My Greene Co. PA and Crawford Co PA Fonners came from Hunterdon Co, NJ, but I have not been able to connect the two families. I have seen Fonner's in Blair Co. PA and elsewhere in PA but have not been able to connect them either. I will keep an eye out for her.
