Gaylon, you might start by going to the Yocom (note spelling) message board in Family History.com. When you get there check the children of Jacob Yoakum (b 1732 d 1780) and his wife Elizabeth. They had eight children, some or all having been in Kentucky. I know that Martha was not a daughter of my direct ancestor Jacob (jr b1767) but she could have been a daughter of Michael (b 1759), George (b 1763), Solomon (b 1769), Matthias (b 1771) or Issac (b 1773).
