This is part of the reason that while I have addresses with my real name, I usually use my alias. I consider it actually a bit odd that with my generation (grew up in the 90s) there's a significant portion of us that picked an alias and have had that alias for a very large portion of our lives, for me it's about 2/3 of my life.
Though to be honest even my own mother can't remember my email address even though I've had the same one for over a decade now. (HN username @ yahoo is one i've had for a long time).
I use a couple different emails for different purposes myself. A couple different names I use online for most things and my first initial last name for more professional stuff (ie: resumes, clients, etc)
