I have a Henry Lantron/Lantrum b. ca 1820 with son Joseph. I don't know where they were before 1850 but probably in TN after 1850 and definitely Joseph was there 1870 as found on census in Williamson Co.
Family says there are ties to MS. Joseph stated inpension he knew people in Al and GA as well as TN where he lived at the time of the civil war.
Any idea on your George w.locations or further? He's about the right age to be my Henry's brother.
