What would you do? 😞 (cousin copied our baby name)

My husband and I found out months ago that we were having a baby girl and we revealed her name to everyone and every post we have done on social media has been with that name. My husbands cousin just had a baby that was a surprise for the gender and we just found out they decided to name their baby the same name that we chose 😞 I’m not sure what to do since we do see that family a lot. I’m still so shocked they would name their girl the same thing knowing we had chosen that name. Would you change the name that you had decided on or still use it?
