It's been over three years since I last responded and was wondering if you are still doing any research? I lost my dad about a year ago, and it has rekindled my interest in the Porter family--my dad researched for years and gave me my interest and push to finish this line--if that is possible!!
I don't think I answered your last question. I have a sibling named Mary but no spouse.
I'm attaching some info from Porter wills in SC that I've found.
