Solange

Solange is pronounced sol-AWnZH in French. The _an_ is nasalised. [noted -ed]

In French pronounced sohl-aw(n)j. I agree with the previous poster who commented about the presence of the French word "ange" or "angel" in this name and would like to add that the word "sol" in French means "alone" or "only, depending on the context it's used. So, Solange could mean "Solitary Angel" alternatively.
