You can submit all of the applications (you, your mother and sisters) at the same time with one set of proof/papers. The fee would be the same, but it does cut down on copying all of the records.
There are a number of Benjamin Harrisons listed, but none with those dates.
There is a Peter Rape, but not with those dates.
Quite a few Crawfords, but no Archibald.
You can easily access the GRS system and look up patriots on the DAR website.
The easiest way to check where you are missing proof is to complete the worksheet, then match up/check off all of the dates with the proof you have. That will show you what you are missing.
