We would love to have the Nemaha County info. The Tibbets are a difficult line for us to trace as we know the connection by adoption and are trying to confirm whether there is also a blood connection. We are finding very limited info on them. It would seeem, though, that the possibility of two unrelated Tibbets lines in that part of Nebraska at that time would be unlikely, so any info you have may provide clues we didn't have before.
Please let us know what info of ours you might need. We now have some death and marriage certificates we ordered from IL and Cali., and we've ID'd a few more photos.
