Begin your family history by recording information you already know. This can be accomplished through a family tree computer program or website, or simply recording the information on paper charts. Either way is acceptable if done consistently and accurately. Once you record what you already know, ask older relatives what they remember. This can be accomplished through interviews, either in person or via phone, letter, or online. In any case, ask specific questions, for example: "Do you remember when Grandma Martha Washington was born?" as opposed to “Can you tell me about the Washington family?” Once you have some details recorded in your tree, you will notice what's missing. Make a list of the information you lack, then determine what type of source might help in finding that information. For example, if you want to discover when your father was born, try looking at vital records.
