Section numbers in Clay County
I am wondering if when Randolph County ceded land to form Clay County in the 1870's, did the section numbers in the townships change? I have an ancestor, Thomas N. Pyburn, who farmed section 26, Township 20, Range 3 in Clay County in 1910-1917. I found a Benjamin Pyburn farming in Randolph County in 1834 farming Section 29, Section 20, Range 3. Any ideas?
