Congress established the United States Military District in 1796 by an act to provide bounty land for Revolutionary War officers and soldiers. District lands consisted of 2.6 million acres in twelve Ohio counties, including Delaware County. The Union Land Company, organized by James Kilbourne of Connecticut in 1806, was formed to purchase Military District land. Kilbourne purchased 4,000 acres in southeast Liberty Township, Delaware County for $7,000, and, in turn, sold the land to 26 Union Land Company members for $2.00 per acre. Five members were from the Case family, and they purchased 950 acres–Ambrose, George, Jonathan, Seth, and Silas. George and Seth were Revolutionary War veterans who did not claim their bounty lands. George purchased lot 11, a part of which is in northwest Highbanks Park today, and Seth purchased 300 acres north of this site. By 1849 the Case family owned over 1,000 acres.
