I'm calling fraud on her claim of 500,00 names over 'months.' Even if done over a year, that's more than a thousand names a day. Before 1860 or 1850, the US Census records only list the name of the head of household, and the number of persons by sex by decade of age in the household. If you want their names, then you need to find wills and deeds or family bibles - primary records, many of which are in private hands or in courthouses and are not accessible online.
Published family histories by the DAR or others are not accurate (I have one documented Revolutionary War ancestor who is claimed on over thirty different accepted DAR genealogical records).
Please 'splain how she had time to go through primary family records for over a thousand people a day for months on end.
I've easily spend weeks working on a single name when looking at the pre-1850 period. I realize these were prominent families - but she still looked at over 500,000 names. At a thousand a day, and five minutes each (riiiiiiiiiiight), that's 83 hours per day.

Doubtless that is true. My grandma isn't in any records I've found anywhere, and I have her letter of acceptance by her local chapter. That was a big deal in small towns. I was never interested. I only have two or three who fought, and would have a hard time proving any of them with the exactitude they should require. I think their records can be an aid if you do more independent research. A mistake can get replicated indefinitely.
I am also a family genealogist. I am with you. impossible. Weeks how about months on one name! LOL. It is fun though.
Happy Hunting.
