Yes, I do have some information on Roland Falwell. I had a conversation a few years ago in the message boards concerning Roland and Robert Falwell of Virginia. I believe that at that time it was theorized that Robert and Roland were closely related (probably brothers). Both men appear to have been born in Buckingham County, Virginia and both moved to Missouri. I think that there is a letter in existence that details Roland and his families trip to Missouri.
The records that I have are mostly property tax records and land records. According to my records Roland first appears in 1829 Personal Property Tax Records. He is living in District #2 of Buckingham County. He appears intermittently between 1831 - 1839. He is often listed as Roland C Falwell.
In 1837 Buckingham County Land Records. He is listed as Roland D Falwell. His land is 20 miles southwest of the town of Buckingham. He lives closest to Robert Falwell. Roland owned about 87 acres.
Does any of this help? I may have some additional information but it will take a little bit of digging.
