1. WDYT?
I don't like it. The Blai part sounds almost exactly like the Swedish word for ew! And it reminds me of the movie the Exorcist. I don't know why.
2. Do you know anyone with this name?
No
5. WDYT would be some good MN's?
I don't know. If it's for a boy I think Blair Alexander is quite nice
6. Does it do better as a MN in and of itself, like for Caitlin Blair?
Much better as a middle name, especially if it's for a girl
