I have gotten a lot of good information from Family Search. I always check the source when it is available, but without that information in the first place, I wouldn't have had any idea that it existed. If it proves wrong, then I don't use it. There were NO on-line sources that I found when I first got on the internet that you didn't have to pay for, except Family Search. I had belonged to several Genealogical Societies, and roamed from Library to church to Library to church for my research also.
