I know of what you speak: in the last week (almost) I have created what feels like 100 profiles but is actually more like 18-20, and I have redone research, and have two or three lines of bio, and so many sources to support that one person was born in one year. And as I write the profile, it looks like I'm doing so much and then I get it out of edit mode, and see I wrote three very accurate sentences with lots of documentation, or I wrote many interesting sentences, in which I'm asking the reader to engage with me, and have two or three resources; last of all is the desperate call to add more family to your tree (and you've already done the research), but you want that person out there, so you write a bland, and short bio, and provide two-four sources, and know you have to go back.
The above was telling you I know how you feel, but, while it does take hours to redo research or to reconfirm it, you need to step back and feel good about yourself and what you have done. It's essential that we spend time confirming resources, and that and writing a bio for one of your ancestors (or for an orphaned person, who is orphaned because the manager of the profile--for whatever reason--is no longer able to work on the profile) is one of the most beautiful things you can do,
And you're doing it--and it takes a lot of time--but you're doing something for your grandfather that he would never have expected. Good luck, and pat yourself on the back for taking the time to find and document those sources.
My curse is the curse of the typo. :)
