Aside from Disney, genealogy is number 2 on my hobby/surfing list. I also use rootsweb.com - no subscription required. You might also search for the specific county's genealogy. In some areas, folks with genealogical interests have transcribed and posted data.
Also, if you're interested, you can PM me. I have access to census records on Heritage Quest via my local library online. 1940 census records are now available (they are "released" at the 70 year mark). So if you have someone born in 1930 but not sure if it was before/after the census was taken, the 1940 one might be a better bet! These are actual census records images and can provide you with a wealth of info. Please PM me if you're interested. I don't always check in on the dis - but can give you my genealogy email addy!
Good luck to you!

. I decided to not push that point with my mother. 
I was surprised to see that Heritage Quest was so incomplete for 1930. There are only a handful of states loaded. It was only after entering a name like "Smith" and not finding any in Massachusetts that I got suspicious.
