Have you ever had a name change? First, commonly known as, surname? How about ancestors?

[uppityperson]

Have you ever had a name change? Either first/commonly used name or surname? Was it as a nickname? Was it changed after you got married, or divorced, or adopted or some other legal type thing? What about your ancestors? How about forums and/or hobbies/work?

My paternal line surname was changed when they immigrated to the USA. I went, briefly, by a husband's last name before it was too weird and my uppityness asserted itself. I was known by a diminutive of my name when I was a child, and still called that by a parent. I've been known as "x's mom" over the last number yrs. I am known as "uppityperson" on DU and another name on another anonymous forum. I have a stage name for stage name.

I considered changing my name to a more "girly" name when I was a kid, and then had an different name as a teen to give to people who bugged me for my name and I didn't want them to know who I was.

How about you?
(edited to clarify "stage name")
