The Oath of Allegiance needs to be signed between 1784 and 1815. This information is not for the DAR. It is one of the ways for an ancestor to qualify your for Daughters of 1812. I have a copy of Ethan's signing of the Oath from a reference book, but he did it before 1784.A better bet is that he or possibly Ethan (who is pretty old by 1784) served in some sort of civil capacity on a local, county or state level. Even something as 'lowly' as being a juror is an acceptable service. As long as that 'civil service' is between 1784 and 1815.
