Catharine Wood, widow of Jonathan the 1812 soldier, did not get "bounty land". She did not get land at all, anywhere. What she got was a "bounty land warrant" for her husband's service. This was a paper certificate that could be used to patent 160 acres of land.
Jonathan had not served long enough, apparently, to qualify for a bounty land warrant immediately after the war, but in 1855 Congress relaxed the requirements and granted more bounty land to all veterans retroactively, as long as they or their widows or heirs could prove that the veteran had served for long enough and had been honorably discharged.
Catharine would have applied for this bounty land warrant in 1855, and she would have received a fancy warrant certificate. She had the choice to either used the warrant to get 160 acres of free land for herself, or she could sell the warrant to someone else. She apparently sold the warrant to Wilcox and Jackson, who then selected land in Wisconsin. Why do you think she didn't sign the warrant over to them? Most widows sold the bounty land warrants because they needed the cash.
In order to apply for and receive the bounty land warrant, Catharine would have had to prove her husband's service and honorable discharge, and prove that she had been legally married to him and was his heir.
If you need Catharine's maiden name, the bounty land warrant application file at NARA would have it, along with their wedding date and place. Also, the surrendered bounty land warrant file at NARA would have the actual bounty land warrant certificate, and on the back of the certificate would be where Catharine signed it over to the buyers.
