what do you think of the name Tallulah?

T🌸
Hubs and I have started passing names back and forth and he came up with this one, it originates as an Irish or Choctaw name (different websites say different things) and means running water. We want a name that is either from nature or has a meaning that is, like this one, so I think it's going to stay on our list... thoughts? 
Our other girl names are: 
Rainier (ray-neer), like Mt Rainier in WA 
River
Sparrow
Hazel (his aunts name, she recently passed) 
Elliott
Naomi
