I'd change it to something less traditional and less common. I was always the 3rd or 4th Helen in my class at school and would often get confused and mixed up with other Helen's. Instead, I'd change it for something more mystical or nature inspired. I'm loving some of the names beginning with I - like India and Isla, and I also like traditional mens names that girls can use too like Sydney and Scout. I wouldn't go too out there though.
I like my name, even though people tend to pronounce it many different ways or put an "a" on the end. However, I always liked the name Eloise. If I had kids I was always going to name my little girl Eloise. Unfortunately, we couldn't have children so that didn't happen. And it's not such a great name for the pet cat hahaha.
My first name is just TOO religious! Would just shorten it, which I did when I started work a million years' ago! Have been known by that ever since. But still have to use longer name for all things legal eg bank accounts etc etc etc.
I wouldn't change my real name at all. Only one other girl with the same name in all the years I was at school. However for some odd reason quite a few people have called me Margaret which is nowhere near my name. I did ask one of them why she thought my name was Margaret as I'd been called it before and the answer was "because you look like a Margaret".
I like my 2nd name, which is what I've usually been called by. (My 3 siblings were also always called by their 2nd names) My 1st name is Carol, after my father Carl, but i would rather it had been Carla. When I 1st visited Paris, I'd always thought, if the name I use all the time, HAD to be changed, I would have loved it to have been...Paris or Isabella!
