Spelling of our daughters name

We are naming our daughter Tahlia Jane Diann. My SO thinks Tahlia should be spelled without the “h”, Diann with an “e” and that we should switch the middle names around. Her last name will be Johnson so I don’t think Jane Johnson would go good together with 2 Js back to back. I don’t want the “e” on Diann because it’s after both our mothers, his spelt Dianne and mine spelt Diane and I just like the way Tahlia looks with the “h”. What does everyone else think??
