Here's one more form I use: a Genealogical Concept Map. It is one of my favorites.
At a glance I have quite a lot of helpful information. I put the ancestor's name in pen and add other information in pencil so it can be corrected or added to as I find more definitive sources. This form, combined with the Checklist for Completed Searches that I posted a few days ago or an updated one at Me and My Ancestors, gives a concise overview of what I need to know when I'm researching -- and space to add more information I have or might need for a research trip.
It doesn't have sources on it because I use this in conjunction with my research log where I keep a detailed record of where I've searched and what I've found (or, in so many cases, haven't found).
I found this years ago when I was thinking about doing my family history and I thought it might be helpful and copied it. Unfortunately I didn't note where I found it. If any readers know its source, please let me know and I'll remove it if it violates copyright or give credit if permission is given by the creator to leave it here.
