All these stories are very interesting, so I thought I'd add mine to the mix.
I was born Florence Ann Blair but always called Ann. When I married the first time, I dropped the Blair and added my husband's last name. But some official paperwork requires a maiden name, and I needed the Ann because I was never called Florence. When we divorced 30 years later, I kept his name, partly because my kids and grandkids have his name. But then I married again. At that time, I dropped husband-#1's name and took husband #2's name. But that made my drivers license name: Florence Blair Humphries, because they refused to add the Ann. So after a year, I went to court and got the Florence dropped. Now I'm legally Ann Blair Humphries and I like it !!! That's how I sign most quilts.
