What's In A Name?

When I worked in Louisville, there were two co-workers named Alison and Allison. After some time, folks just started calling Alison "One L" and the other co-worker Allison.

I tell you this because I'm in the middle of a "One L" dilemma myself. Or is it dillemma?

I think my birth certificate lists my name as John Phillip Wise, though I've used John Philip Wise when filling out important forms and so forth. Or perhaps vice versa. Either way, I know my birth certificate shows it one way and I use the other way. So Mom, if you're reading, is it one L or two?

Thanks a llot.
