Those (Bounty Land Number) are just the warrant numbers. The warrant just authorized the person to go claim some government land set aside for this purpose. Kentucky and Ohio were bounty land for Revolutionary War soldiers, land even father west (places like what are now Illinois, Arkansas, and Missouri for example) was allotted for War of 1812 vets. It was kind of like homesteading in the sense that there were tracts of land available to you, you went and found a piece you liked, and then obtained a patent.
