Rootsweb also great for checking for family trees (free)

I just entered a search example for "Joseph Smith" ... scroll down to the bottom of the page to see the boxes where to enter information for your search (names, dates, place, etc ... you don't have to enter info in all the boxes. Even just a surname brings up family trees links, but the more info you can enter narrows the search and the number of hits)

Hope someone finds this helpful!
