Baby names

I’m nearly 24 weeks pregnant and not finding out what I’m having until it’s born.

My partner and I have agreed on a definite boy name, but unsure on a girls name.

My dilemma is, I had my heart set on a particular girls name, but my dad’s partner’s daughter, who has multiple kids and is only 26, has used the name I wanted, for her daughter.

I have no relations with this person, except for dad being a mutual family member; but I don’t want to use names that have already been used on either side of the family.

What should I do? I can’t find another name that really grabs my attention as I had my heart set on that name. Help 😰
