It's a natural human curiosity to want to know where you came from. Not knowing where to start can often be the daunting part but once you make the initial queries and discover some interesting facts it often leads to further lines of enquiry. Before you know it you have gathered a wealth of information you would never have known had you not taken that first step. Researching your family history is a very rewarding yet time consuming project but I'm sure you'll agree, it's well worth the effort.
If you just starting out and not sure where to look, I have put together a list of links to help you with your search. Good luck!
