One of the easiest ways to get information about your ancestors is to copy the hints given by other members of ancestry.com. Many times these hints are reliable, but only those that have documentation to back-up their claims. I have received emails from individuals claiming to be my family member, when they really were not. It only took me about five minutes of digging to find that this person was way off. Going through ancestry.com member hints can make your jobs a lot easier, but it is always a good idea to do the research and back yourself up with records and other documents. The only time you might not need a reference is when you are a direct family member that talks to the actual ancestor. Although you might want to reference the person, they don't always want you too. Some individuals are very scared of the internet and the exposure it give to their personal life. So yes, use ancestry.com's member hints, but no, don't take their word for it. You may find you wasted a lot of time adding all these people that were never related to you.
