Hi Diane - since Tillman was already married in 1870 - and not living with any other family memembers other than wife and children - there is no way for me to find his brothers and or sisters in census records. Your best bet is to find someone who is also researching Wimberly - who has some clues to that specific family.

If you can get a marriage license for him - it would help - perhaps identifying his parents. You would then have to find other Wimberleys from the county who also listed the same parents.
