Baby name help

I’m 31 weeks and I still don’t know if I love any of my baby names. I want to have the name before December since I plan on getting everyone’s names embroidered on our Christmas stockings lol. My first boy is named Leo and I’m having another boy. Our names on the list so far are Luca, Lincoln, Mateo, Koa (pronounced like Noah) wanting to know what boy names you guys think would also go with Leo for a brother! Thanks in advance!!
