To me Graciela is a more refreshing, and interesting choice than Grace. First and middle name. So beautiful, and soft. It’s a nice name I would be happy to consider.
I notice the ciel in Graciela. Ciel means sky in French. Ark-en-ciel means rainbow in French (literally "arc in the sky"). When I see Graciela I think "graceful rainbow." It also seems multicultural because it is a Spanish name with a French word in it (which I am fully aware is not actually related to this name.) Pretty!
