Don't get me wrong--I really love Footnote, but it is irritating when promotional materials get factual details incorrect as this ad does for Footnote's Revolutionary War Collection of Materials.
This ad for Footnote's current offer indicates one of the documents as a "Revolutionary War Court Appearance." The referenced document is from testimony in a Revolutionary War Pension file--apparently in September of 1820.
I use Footnote.'s collection of Revolutionary War materials regularly and like it a lot.
