Secret names

Is there anyone who keeps their names as secret as possible? We have a Claribel James and a Jupiter Scott. Both girls have pretty rare names, after being named Nevada and not ever meeting another that was the goal. We’re due in April with our next and I have a name picked from before we ever got pregnant. I love it. I was on the phone with my dad when it popped into my head and blurted it out. He also loved it. The middle name will be my dad’s middle name (Ray.) my dad passed from cancer June 27th so we never go to tell him we were pregnant again. I have a sis in law wanting to know the name to get a shirt made for our mom in law but I don’t want her getting something custom made through someone else because they could 1 steal the name, 2 post a picture of the product on social media and others may use it, 3 talk about it and someone hear it and take it. I know it probably sounds crazy but this name is the rarest name I have come up with and is only used on average once a year when I looked it up the day I thought of it (probably 2 years ago, now). I won’t even google it again because I’m scared it will recognize an uptick on it. 😅 Am I nuts? I’ve just met too many name stealers and my other sis in law grew up with a girl in a small town and we’re pretty close friends and that girl stole my sis in laws name for her daughter down to the spelling, even. I have a cousin that tried to use my daughters oldest name because “it’s a family name” like I’m not prepared if someone uses this name before I get to because they heard it or saw it before the baby is born.
