My given name is Wichita, this has caused issues since I was in first grade. I was born and raised in a small town in Arizona, Ajo, with a large percentage of the population speaking Spanish. In Spanish most nouns end in either a or o, the a denoting female the o denoting male. I'm male and this caused some issues.
My brothers name is Waco, so it's Wichita and Waco; but it gets worse. Middle names are Zane and Shane; so it's Wichita Zane and Waco Shane, couldn't make that up if I tried.
I live in Pocatello, Idaho. While I was in the military there was an investigation; during my interview, I was asked several questions: Name? Wichita, spell it? Home of Record? Ajo, Arizona, spell it? Permanent Address Pocatello Idaho... ... ... Get the heck outta here, there's no way you would do anything! You're way to memorable.
In the early 90's I used the local BBS's (pre internet) and since shortened name were a thing, my username was Wich. This caused some issues because other users couldn't tell my gender or if I was wiccan. So I changed it to wichman, years later I found out that Wichman is an actual surname, who knew?
Anywhoo that's how the user name of wichman came about.
Thanks for reading.
