Hi, Thanks!!!!! for contacting me. I'll be anxious to see what you have. Others have told me about Reuben Jackson, but I've never been able to find the connection to my Isaac. There are two Isaac Jacksons that took almost the same path from Kentucky to Missour and, obviously one of those Isaacs isn't mine... and I always thought the wrong Isaac was the son of Reuben. But, I could be wrong... Nevertheless, you seem to have the Brock connection. I can give you an e-address to send further correspondence if you'd like.
