On a list of heirs of Reece Morgan (William's father) in an
1890 land lawsuit, the following are included in the
list of defendants (which is pretty much Reece's heirs):
Edward Morgan, Zwingler Morgan, Jese Morgan.
It is my guess that these are probably the sons of either
William and/or William's brother James and that William
and James have died by then since they aren't named in the suit.
Census: 1860, Lexington Twp,Scott Co., Indiana
