Did you change your horses name?

I see a lot of people asking what to name their horse. My grandparents bought my aunt's first horse at a sale. since we never knew her old barn name so we obviously gave her a new one. Every other horse i've had since then i've just kept the same name they had when i got them except for my own first horse who i named Abby because she didnt have a name when i got her. I have a mare named Charlie, I didnt give it to her, nor do i like it, but im not going to change it, shes been called that her whole life, so i dont see the point in calling her something else. anywho, did you change your horses name when you got it? if so, was it because you didnt know its prior name, or just didnt like it. im bored and the HS is pretty blah today
