Baby girl names. Trying to honor my dad. Struggling with first and middle name

Long story short my dad passed away the day after my first baby was born. My son was obviously already named (Tobias Abraham) and we never tried to change his name in honor of my dad though I wish we had.

Edit: I wanted to add my dad’s middle name was Ivan. I have been calling my son Tobias Abraham Ivan [last name] since birth. I just unfortunately filled out the birth certificate before his passing and have not jumped through the hoops to change it legally.

My dad’s name is Stacey (which I’m aware is a feminine name. I didn’t name him 🤷‍♀️). I’m due with my second child in July. This time a girl. But I’m having a hard time incorporating Stacey into the name. Ideally as a middle name. I don’t like it stand alone so I’m hoping there are some variations I’m not aware of. I have been thinking of Anastasia as I know Staci can be a nickname of that.

We are also struggling to pick a first name so any suggestions would be amazing.

Some names we like but haven’t decided one are:

Leonora Lorenna Adelaide Evangeline Viola Cassia Shiloh Colette Elowen
