Surnames have LANGUAGE origins, and they will tell you very little, if anything about person's genealogy or family history. The only way to know your family history and genealogy (who you are related to) is to do the research or pay someone to do it for you, which can get very expensive very quickly. (Professional genealogists charge on average US$20-$23+ an hour.) Start with yourself and work your way backwards, one generation at a time. Gather up your records, such as a birth certificate, marriage certificate (if applicable), newspaper articles and clippings regarding some of your accomplishments, journal entries, etc. Do the same for your parents, grandparents, etc
As you are working on your family history, you are bound to find several spelling variations of first and last names for various reasons. In some areas, the census enumerators were often the only people who could read and spelled names phonetically, based upon how they sounded. Sometimes people made clerical mistakes, etc.
