My sister did one Patriot and once the lineage was confirmed, I could've just done him. But, I chose to do another ancestor. The DAR woman did so much of the work, all I had to do was provide my proof of lineage and I have to get my grandma and grandad's death certificates -- that's easy!
Now all this paperwork goes to Washington, D.C. to their genealogist to officially certify. If the link isn't there, they won't. We have to prove this generational link. They are very serious about this stuff.
Just fyi, it can cost a bit of money if you have to keep sending off for death certificates/marriage license/wills etc... so hopefully you have an Ancestor where the DAR woman can access the records without cost. My sister's patriot cost more money to prove, even though he was a registered numbered soldier, no one had tried to prove the lineage through him yet. mine is costing me 40 bucks. And that is because the ancestor has a American Revolution number already and other relatives laid some of the groundwork to become a Son of the American Revolution or Daughter.
And, if you have a relative who is already an established DAR or SAR (grandma, great grandma, grandad, great grandad etc) etc... and you are blood to them, that would be an easy one to prove your continued lineage.
