By following the links to the search page, then searching the Ancestor Database, you can see a brief summary of accepted service of a DAR Patriot Ancestor, children whose descendants joined DAR, and often some further lineage from each child through whom a woman became a member.
The website information sometimes 'flags' as incorrect some previously-accepted claimed service, but in general it says what has been accepted as proved -- not that "so and so did not have active-duty service."Sometimes active-duty service was not discovered by a DAR applicant due to limited access to resources.
For one of my ancestors, several women joined on the basis of his Pension Application File, but they either did not look at his claimed service record or failed to report what was in it (it says the claimed Patriot Ancestor's claimed service ended in desertion).How he managed to get a pension is not explained :D
In the years prior to the Bicentennial, many things were accepted by DAR on the basis of flimsy evidence.During and after the Bicentennial much better research was done and then required by DAR, which is why no few of the above 'flags' are on the site.Either claimed service or claimed descent may now be questioned that was previously accepted.
