A Facebook friend posted a link to a blog post explaining how to find the names of those who were receiving Revolutionary War and other service pensions using the 1840 US Census. The lists provide the name and age of the pensioner and also name the head-of-household in which the individual was residing.
This is a very valuable research tool and one I was not aware of.
Check out My Kith 'n Kin's blog post The Secret Hiding on the 1840 U.S. Census for full details and examples on how to access this information.
