Cussewago Township is Venango's neighbor to the west. It was created on
July 9, 1800 from parts of Conneaut Township and Mead Township and was
first settled in 1792. It derived its name from Cussewago Creek and is
one of the earliest parts of Crawford County to be settled. The villages
of Crossingville and Mosiertown are located in the township.
The Senecan word "kassewaugo" meant "big belly." According to tradition,
natives gave this name to the creek after discovering a large black snake
that appeared to have swallowed a rabbit.
