If you Google me under my married name, you come up with different, very well known, Elisabeth-with-an-S who wrote about death and dying. We don't have the same last name but it is very similar and a lot of people think (incorrectly) that it is spelled the way I spell my last name.
My maiden name will bring up a lot of genealogy stuff. I am very interested in the subject now but I was really into it in college and so my name appears on message boards and forums all over the place. Genealogy is a subject where you really have to use your own name, otherwise you kind of miss the point!
(and I am still 27!)
