My DAR patriot says new applicants must prove his military service. He is mentioned as one of the founding members patriots. He married Eleanor Dallas. The headstone placed in Ohio says he was in the 5th Va regiment yet I cannot find his name on any muster roles. Relatives found a land grant from the war but the name on it says Capt Robert Sayer. They say it is the same man due to his his and birth and deaths matching. How would one go about proving something that the DAR once held to be true? Any help would be most appreciated. Several are working on this but we seem to go in circles.
