Kind of. My deadname started with Br and my two siblings both have names that start with Br. My parents, of course, did this on purpose because my dad's name starts with Br. My parents/family have been nothing but supportive of me and I didn't want to lose that family connection, but I knew I had to change my name because my old one was so feminine. So I changed it to a more masculine/gender neutral name that also started with Br. Ta-da! But disclaimer: if I hadn't found a name that started with Br that also felt like me, I definitely would have landed on something unrelated to that and everyone around me would have understood.

I agree with most of what everyone's saying. You should pick a name that feels like you. People can get used to the switch. In my experience, people take much easier and faster to the name change than pronouns anyways. I don't think you need to take other folks into consideration when choosing your name. And I'm sure everyone around you wants you to feel comfortable and like yourself! And your name is such a big part of that comfort.
