Boy Name

So I found out that the first name I picked for our son due in October was used by my grandmas niece and middle name by someone on her side of the family. Both people who have used it I don’t even talk to or ever see. I haven’t seen her niece since I was in elementary school and the guy that used middle name for his son, well I never remember ever seeing him. I spoke to my mom and she said who cares. I love the name and use it. So did my in laws. My fiancé doesn’t care either. I love the name so much and I was so set on it. Would it be weird if I use them?
