Some words on the subject by @Alan25main:
"A rose by any other name would smell as sweet. Titles of things often seem arbitrary; if the titles “dog” and “cat” were reversed, and always had been, no one would know or care, least of all the creatures themselves. Those names, often tell us nothing about the thing or creature, itself.
People, on the other hand, are often named in hope that their name will have meaning, at least to those doing the naming. How often do we hear of “X” Junior or the II? Or, some larger number of repetitive naming? Surely the naming persons don’t expect the newest bearer of that name to be a duplicate of the predecessor. They likely hope he/she becomes an improvement over the original. Thus, other than possibly telling us something of family history, those names don’t have much real content until the people bearing them give their name meaning by their actions in life. And, since names are usually conferred on babies while they are still babies, the individual-to-be had no choice or influence in the matter. (A good argument could be made that names do influence who babies grow to become, but that’s a discussion for another day.)
In the modern world, we frequently do get to choose our own names, at least in limited circumstances. User-names for computer gaming or email addresses are a good example. We generally pick those ourselves and often use them to tell something of how we hope the world will see us. Matildabear conveys an entirely different image than Matildabare, for example. The first could be claiming strength or love-ability, the second saying “I’m a very open person,” or “I’m a naturist” or even both. So, an eponymous (self-given) name often does convey information to the reader. What are players hoping to tell us with those names?
A lot of people use their names to describe what they do–or want to do–for work. I haven’t noticed any “shoesalesman” names, but there are numerous medical profession sounding names. A lot of others combine a male-female pair into a single word, BillAngela for example (this is especially common for shared email accounts where both use it). Others refer to their hobbies or favorite pass-times, MasterChessPlayer, for example. I’ve met several incarnations of Dbrunson in online poker games (with variations in spellings), and never for a moment considered that one of them might really be him.
Why and how did you choose the name you play under?"
so I changed it to SharonSmarty
