Names That Mean Solemn

This is a soft, soignée <a href="https://nameberry.com/baby-names/497/french-names-for-girls">French girls' name</a>that has become familiar here via singer Solange Knowles, younger sister of Beyonce.
 It is also the name of a martyred ninth century saint, a poor shepherdess who came to a tragic end while defending her honor. Among other things, St Solange is a patron saint of rain.
 Solange would make a striking, sophisticated choice, though alternative forms include Solenne, Soline, and Solenn, which are currerntly more popular in France. Pronunciation in French: SAW-LAH(n)ZH, though in English, so-LAHNZH (zh like the z of azure or the g of beige) may be heard.
 
Given to 33 girls in the US in a recent year, Solange coincides with the German word for "so long as".
