When I read Emma Helen Valerie I hear "I'm a hill and valley"! But that's probably just me! I agree with OceansEve that Finley Helen Valerie flows very well (unless you hear "finally hill and valley"!!)
Aren't names difficult?! We're trying so hard to find something that has family meaning and have finally (almost) settled on a girl's name, but just can't seem to come up with a boy's name that has any connections at all, with the possible exception of using Leopold as a middle name since we're both biologists who love Aldo Leopold...but that seems kind of a remote connection compared with being named for your grandfather or something. However, with being kid #4 and grandkid #16 in a small extended family, it just seems that most of the names have been taken!
We may have to come to terms with just picking something we like. After all, family names have to start somewhere, right?
Fiona Evelynn is nice! I love Fiona and it goes with DH's last name, but he nixed it because of Fiona Apple (whoever that is).
Andrea, you're welcome to our original list of first names that were supposed to go with Annaliese (sorta similiar to Valerie in cadence) if you'd like...
Or have you considered using Helen Valerie or Valerie Helen, and then using a diminutive form of one of them? Helen has some cute ones-- Ella, Lena, Ellie, Lennie... Good luck!
