This is what I've read about pioneer setttlements in early Greene
County:
The area that became Greene County became available after what was known
as the "New Purchase" of land from the resident Indian tribes was made
by Terrritorial Governor, William Henry Harrison. After the Battle of
Tippecanoe in 1811, with some of the more recalcitrant natives, white
settlers poured into Indiana in increasing numbers , mostly from
Southern states,so that by the time of statehood in 1816, most of the
Indians had been forced out and were no longer a menace.
One of my ancestors secured 160 acres of land in what became Highland
Twp., Greene County, from the Federal Government's Vincennes Land
Offfice ( which handled land sales for the area) in 1818. My wife's
ancestor secured , a similar tract in Daviess County in 1817. In
neither case, was it a Military Land Warrant, but I think some of the
land was provided for veterans of service in the War of 1812 .
Both of our ancestors were farmers and agriculture was the major
attraction for earliest settlers; even though the land was covered with
timber that had to be cleared and often hilly. The latter geography was
not unusual but familiar to settlers from the rugged terrain of Middle
Tennessee and Western North Carolina.
