I have visited the DAR website before but found it somewhat overwhelming. Myrtle went through the site step by step and made it seem simple. During the webinar several people were finding American Revolutionary ancestors. Afterwards, I myself found a few that I didn't know had served. It was exciting and very appropriate for this July 4th weekend.
If you missed this webinar and are a member of the Southern California Genealogical Society then you can still access it in their "Members" section. Otherwise it will cost $35 for a one year membership, and then you will be able to access it. After the webinar I checked out their page and as a genealogical society they have a lot to offer. I myself am not a member, and am just passing the information along.
Wishing you all a very Happy 4th of July!
