One way to track your family history for future generations is to fill in your family tree. If you take the time to do this now, it will be a starting point for someone in the younger generation to keep it going so you will have a record of those who came before you.
Besides having a record of family members, a family tree can also be a source of family medical history so family members can see what illnesses may run in your family. This is important to know so you can report any possible issues to your doctor.
There are several sources of research, there are online ancestry and family history services or public records at the local courthouse for the areas you are interested in. Some of the online services have free or inexpensive services to get you started. If you want further research, there may be fees associated with the services. More in the past years, many families kept track of the family tree records in the family Bible or some other kind of book. This can be a great starting point.
Start with a specific reference point. Start with one part of the family and once you have that done you can work on another one.The information party rocks on: Family Reunion Confidential
