Middle Name Help (EDITED)

I’m 25 weeks and I keep changing the name that I like and I’ve come down to two names:

Salem & Dallas

The problem is I can’t find middle names that would go with either that flow and I not sure if I like the either combo of the two.

Here’s a pic of my sweet boy at his 20 week ultrasound:

EDIT:

I’m not asking for your opinion(s) if you think of either Name is a boys name or a girls name. I’m asking for MIDDLE names. If you can’t suggest a middle name then keep your opinion to yourself 🙄
