I agree with you. All any of us can do (including Trump) in this all important decision process is “guess” based on a few tidbits of facts. One tidbit is that at some point in her life Barrett elected to hyphenate her name. Lagoa did not. Is that an indicator that Barrett is more of a Feminist than Lagoa? Who knows? But, all things considered, I suspect she is. So, I vote for Lagoa.
I have never seen Barretts name hyphenated.
