I am a little over five years into this interest (actually an addiction) of tracing the genealogy of my direct family and related families. I am sometimes asked why do you do it? My answer is twofold ~ a love of history and a sense of appreciation.
First, what's not to love about an interest that takes you on a trip through time, and lets you explore lands and people by studying their geography, religion, architecture, occupations, political beliefs, economies, and culture (their dress, foods, & music). Add visits to libraries, archives, churches, genealogical societies, and cemeteries in near and far off places to the mix ~ and you become a time traveler, an adventurer of sorts. I have an incomplete map and get to go on a treasure hunt!
Second, I truly believe that the more we study our families' stories the greater understanding and appreciation we have for who they were, what they experienced, the choices they made, and the gifts they gave us. Everyone has a story to tell. Oftentimes our ancestors were so busy surviving that they did not have the time or the ability to tell their stories. Thankfully today we have that luxury ~ so I am doing my part to make sure their stories are told.
