Yes and no. I've had opportunities to obtain copies of land and deed records, which would have been able to fill in some gaps as it relates to where families moved, what land they purchased and owned, and when they sold it and presumably moved on - however, most of the records I've wanted have been in states where they won't do research, aren't online, and require you to go to them and do your own searching. Frustrating.
I did find a local researcher and I think I might have asked her for too much, as when she laid out the 30-40 records she was aware of in the files, and then asked me which ones I was most interested in, I told her my top 10, then also said "all" would be useful. I never heard back. So I'm going to apparently have to wait until I can make a 300 mile trip to the county courthouse to do my own research... one of these days.
