I don't think that it really matters what you're called- family members will always mix you up! Bonus points if you all live in the same area, and people outside of the family do it, too!
The women in our family all have very different names. You tend to get a long list of names of family members before you might get to yours, or you just answer to anything (including the cat's name, or an entirely unrelated name that isn't on your birth certificate, but it's what your family calls you). Think: I was christened with an 80's/90's name, but called an old lady name that became fashionable. Interestingly, I got horrified looks for answering to it before its resurgence!
This habit of christening a child one thing and calling them another gets very confusing, to the point that we assumed that we were at the wrong person's funeral, denying that a relation worked somewhere because we didn't have an Uncle X, and a nurse who knew the family changing a relation's name on a hospital board because he was registered as X but known as Y. I'm yet to understand how I knew my official name by the time I got to school...
Most of the men in the family share the same first name. Trying to figure out which one is being spoken about can be fun, as is trying to remember which one is which in phone contact lists... When it was announced that I was having a nephew, the first thing that I said was, "Please don't call him <insert duplicate name>!" Thankfully, it's not even a middle name😆
