*Rayna was played by Mrs. Coach *Taylor, so I'm not sure if you're crushing as hard as I am on Connie Britton, or it's just coincidence, buuuut... yeah.
Nashville is where I heard the name first and loved it....But not naming her after the character. And I think Taylor is to close to and to common, but my husband likes that name.
I actually think that Rayna is a pretty standard spelling as an eastern European name. I once knew a Bulgarian girl by that name spelled that way, aged it shows up on Behind the Name that way I am sure people would often spell it the Spanish way (Reina) though, as pps here have, so that's something to consider. I think Taylor is too similar to your dds name and would definitely go with Rayna. Here are some other names with a y in the middle if you are still looking:
