Medieval Names: Common vs Uncommon

I recently made an unhappy discovery on my old desktop computer: the file that contains my carefully compiled list of medieval names has become "corrupted!" Fortunately for me, I have a physical printout of the names. Unfortunately, this means laboriously typing the lists into my MacBook so I have a backup copy. (Yes, I could simply scan them in, but I want the flexibility of being able to add new names as I find them.)

My bad luck is your good fortune, since I'm feeling in a sharing kind of mood. Here is a list of "common" vs "uncommon" names in medieval England. These particular names were extracted from The Oxford Dictionary of English Christian Names, by E.G. Withycombe. (Oh, these are all male names. I haven't retyped my list of female names yet.)
