Name drama

Lauren • Wife, J • 3.2017 💕 Boy Mom, A • 7.2016 + A • 12.2018 + A • 8.2020 💕

So my fiance and i had a name picked out for our boy that we both agreed on almost instantly. I recently noticed that my fiance's obsessive ex who had her baby a few months ago named her child something very similar to what we have picked out. Is that something I should consider to change the name we have picked out or should I just ignore it?

Edit: the name we chose was Cian. Her son's name is Liam. We thought of it before even hearing what she named her son.
