I just found your message. I've been researching Jimcey Mott and have also hit a brick wall. I've been unable to find any info. on his parents or siblings (if any). He was my great-great grandfather thru Cincie Pike Mott. I have never seen the name Rebecca McKim. There aren't any McKims or Hensarlings on my tree. You are welcome to look at my tree to see if it can help. I have his DOB as circa 1847 from Mississippi but that's all the info. I got. If you have found any info. I'd love to know.
You are welcome to email me at

Good Luck!
