Aww, what a sweet idea to combine your names! From Aliana Cherryl and Jay ar (assuming Jay ar is short for Ceferino?), you could try Alian + Jay = Aliay or Jayiana, or mix Cherryl + Ceferino = Cherino or Ceryl, honestly, the combinations are endless and so cute! A few of us moms did this too, and we just tried different mixes until one felt right, so maybe sit with each one for a day or two and see what feels like your baby, you know?
