Choosing a name is so hard!!

We have been about 80% set on Lorelei throughout this pregnancy but we discussed it again tonight and we've both gone off it a little bit.

DH suggested Seren tonight..... which was really high on my list a few months ago but he vetoed it! But now he really loves it......and I might love it too.... (although its a shock to the system, I was so used to Lorelei)

Seren is a Welsh name and it means star. Any ideas for a middle name? Our last name has two syllables and ends in ee (think Bromley).

Thank you
Edit: Pronounced seh-ren (seh as in sent and ren as in rent)
