Caroline, yes, I am a member of the DAR, a wonderful organization. A family member, a descendant of the Patriot as you are, completed an application to join the DAR, that is why this line is recorded. You will be asked to prove YOUR line. All you must do is contact your local DAR organization and tell them about your Patriot, show them the membership information and they will assign someone to help you prove your lineage. You will be asked to prove each link..from yourself to your ancestor. They are only to happy to offer you some assistance. Just ask.
You will be asked for vital records, etc. to prove that you are, indeed, a descendant.
