How long are the limbs on this family tree?

A few months ago my mother paid for a year's membership on ancestry.com to research our family. We are mainly interested in the Irish part of the family; myself even more so since visiting Ireland in October of 2009 for my honeymoon. Yesterday mom gave me the login information so I could help research. I reached several dead ends and was a bit discouraged until researching my great grandmother's paternal line. With the help of other established family trees I traced the line back to 16th century Germany. The last name is very French sounding so we are sure that there's more to the story. I plan on pursuing it further at a later time.
While working on this my husband wanted me to look into his family. Leigh is traditionally a Welsh last name, so we expected to see English immigrants on his tree. I found so much more than that. His great-great grandfather, Osmer Cornelius Leigh's family originally came to America in 1621. Along the way it produced veterans of every war our country has been involved in. From the solider in the Revolution to Grandpa Johnnie in WW2 and even more recent conflicts. But our information didn't stop there. I can safely estimate that I've spent at least 12 solid hours uncovering the aristocracy Jesse comes from. There are Viking kings, Scottish princesses, and even a saint. As I take a break to write this blog my other window contains information on Hugh II "Le Mefiant" Count of Tours. Born 756 in Orléans, Loiret, Centre, France, and died 836 Lot-et-Garonne, Aquitaine, France. This is all very fascinating, especially since nobility is well documented, making it simpler to research the family lines. Intermarrying between royal houses was very common and very apparent in his history. My plan is to follow each line back as far as possible before moving on to the next. I had hoped to have a respectable history to give to the family when we visit them next week, but I somehow don't think I'll be done uncovering it by then! I can't wait to see their reaction when I give them the highlights of their history.
