Posey co was formed in 1814 with an effective date of Nov 1, 1814. This would have included the area that is now Evansville. Vanderburgh Co, including Evansville, was split from Posey effective until Feb 1, 1818. Maybe news was a little slow back then.

However, one place listed them as living in Evansville, Posey Co. On my 1999 AAA map of IN, it shows Evansville as being in Vanderburgh Co. Was there a split and how recent was it? Appreciate any help. > Vicky Cannon
