Baby name

So I was just scrolling on Instagram and found a girl we have mutual followers so obviously she lives in the area but she has a lil baby and I was looking at her account and her sons name is the name I wanted to name my son if I was having a boy😕 because me and my boyfriend wanted to compromise and he wanted the name Oliver and I wanted Killian well her sons name is Oliver Killian. I don't know if I should just avoid naming my son that because I feel like some of our mutuals would be like "you copied his name"😢
