On December 16, 2011 I received a copy of the complete Military Bounty-Land Warrant Application File - Warrant No. 87463 from the United States National Archives & Records Administration containing 16 pages for Clark Crocker, Veteran War 1812, Capt Hamilton, Georgia Militia. Served 14 Nov 1814 to 09 Mar 1815.
And this file shows that Clark Crocker died October 21, 1854 in Lauderdale County, Mississippi.
