Twin Names

So I’m pregnant with twins and we are torn atm about finding out genders. These will be our last babies. So we need to come up with 4 names in case we choose not to find out lol. My fiancé sons name is Elijah Jordan, my sons are Steven Douglas and Sawyer River and our daughter is Stella Rayne. Idk if I wanna stick with S names but all my other kids have S names lol.

Names I’m contemplating:

B/G Arlo and Amara (unsure about middle names)

Another boy name I like is Salem and Ambrose

I can’t come up with any other girls names tho....

Any suggestions greatly appreciated(:

Also looking for middle name ideas preferably that start with the letter R (:
