If you are wanting to find ways to find more information about your ancestors, this post by historian Ardis Parshall is a goldmine of information.
Dance, Dry Bones, Dance
(Oooo. I love the title, too.)
She's done other posts on family history as well.
Lesson 1 (First steps)
Lesson 2 (Home sources)
Lesson 3 (Social Security)
Lesson 4 (Census)
Lesson 5 (Resolving Discrepancies)
She has a gift, I tell you, and it's a gift that she shares it.
And if you are interested in reading history, you'll want to sit down for a while at her blog. Amazing stuff, particularly if your interest is in Mormon history. (But it's not the typical LDS history she writes about. She shares stories that are less-known, if known at all.)
