Should I care?

So I changed my daughters name to kylie.

Here's my issue...

My dad was married for 13 years to my step mom and when i graduated they separated and this year they divorced. My step brother and his wife and kids live with my dad and they are still family to me and I see them all the time, also I see my step sister a lot too. I grew up with them so it's hard to not consider them family now that by marriage we aren't legally family. Well my step-mom (who never tries to see me or talk to me or show any care whatsoever, or treat me as her daughter ) has a brother who has a daughter named kylie. I haven't seen her in 2 years and I never am even treated as family to them. That doesn't bother me but do you think it should bother me that my daughter is being named the same thing as her? The only people who have to deal with the two different Kylie's are my step siblings but they aren't ever in the same place so it wouldn't be too confusing. If I don't ever see her or him and I love the name then should I still go with it? I'm sorry if that was all Confusing.
