Hi Bex !!!
I'm quite familiar with
Lucienne as French names have been the more familiar foreign names in my area for centuries (the dialect that my father speaks has a lot of French little influences).
We have an Italian form of it:
Luciana (popular on women born in years 1960-1979) but it is slowly disappearing (in 2016 only 19
Luciana).
Lucienne is far better than it.
It enough vintage to be ready for a comeback out of
France imo. It is fascinating and less popular than
Lucille (but I still prefer it).
I read that someone told you that
Lucienne is too French to be paired with
Theodora. I think that they share an unusual, elegant, vintage vibe that makes them unique without being tacky or weird.
I'm quite worried about your combo
Winifred Rowena Lucienne?
All three names are long, sophisticated with a N, R and a W/U sound. They seem a list. They are too much together imo.
If they are honouring so no problem but I would choose some other possible combos. At least only two of them with a shorter and simplier one.
If you have any idea or you like to ask for them I would be glad to comment.
