If your ancestors have passed down rumours of royal blood, or of links to the rich and famous, what should you do?
A good starting point is to follow the story to as near to the source as possible, and interview those family members (preferably on tape or video if they are willing). This will give you information to use as a starting point for your research. Very often there is more than a grain of truth in stories passed down through the generations.
Once you are armed with all the information you can glean from your relatives, work back along the family line to find the ancestor with the royal link. Genealogy websites, such as TheGenealogist can help with this.
These include census records, birth, marriage and death records, parish records, directories, military records and more. You can find information on tracing your ancestry at British-Family-History.co.uk, a simple guide to researching your family history. This site include lots of information on the different types of records and how to use them, and lots more about genealogy and family history. It's a fantastic guide for beginners.
TheGenealogist has a whole section of its website dedicated to Peerage, Gentry and royalty records, which are worth looking through if one of your ancestors had a title or was a member of the aristocracy.
