The only 1812 soldiers eligible for land under the Act of 1812 were the federal "regular army" soldiers, not the state volunteers. So if your soldier claimed land under this act, he should have an enlistment record on microfilm at NARA. I believe ancestry.com also has this microfilm. If you do not have a subscription, you should be able to view it for free at your local library or research facility that has an ancestry subscription. The enlistment record should give some personal information such as age, description, and place of birth. Best wishes.
