I don't really like
Liesbeth, but this is the first time I've ever seen it before. I think
Liesl would work just fine as a nn, in fact I love that name. (Though I prefer
Liesel, and not as a nn, just by itself.)
Adeline is a great name and I'm glad to it's in your combo! I like this spelling of
Elisabeth, and I think
Liesl would work great as a nn for it as well. I might slightly prefer
Elisabeth over
Liesbeth.
