Baby name

My husband and I love the name Aiden for a boy, the only name we have 100 percent agreed on. My stepsister is almost 10 years older than me and we don’t have much of a relationship.. she named her son Xaiden (pronounced Zaiden). I feel like we can’t use Aiden now because they are too close? What do you think? Just use it or should we find a new name? 😩
