I also do not have a Ruth Yocum/Yoakum. Don't dispare, sometimes these things take a while to sort out but some where out there is the key to the puzzle. I am in contact with a couple of others who are researching Yocum (by the way, my grandmother was the only one in her family to spell it that way, all the others used Yoakum, and the original spelling was Jochem), I just yesterday put the Yoakum story on my web page. This particular story was the first I found many years ago and was authored, I think by the Palatines to America Assn, even though Jochem was not a technically a Palatine. That phrase is usually reserved for the 1709ers and the Yoakums came here earlier than that.
If you are interested you can go there and see what my line consists of. I have a lot more yoakums since then but haven't organized it for a page as yet. aCastleman@aol.com
