Cassia is related to the cassia tree, which has yellow flowers and produces a spice that can be a substitute for cinnamon. Keziah, the name of Job’s daughter in the Old Testament, derives from the name of the plant as well. Cassia also has ties to the Ancient Roman name Cassius, an Ancient Roman family name meaning "hollow."

Kassia is the k-styled spelling variation of rising star name Cassia, an obscure but attractive botanical choice drawn from the cassia tree, which produces a cinnamon-like spice. The biblical Keziah is related.

Kassian may be seen as a Kardashianed spelling of the rising saint's name Cassian, which is a variation of Cassius, but it could also be considered the authentic Greek male form of Kassiani, the name of a female saint revered as a hymnographer. However you spell it, this is an attractive and unusual name virtually unused in the US -- though we predict that will soon change. If you're hunting for unusual yet stylish Greek baby names, variations of this name should be on your short list.

We've long been a fan of spice and herb names -- Saffron, Sage, Juniper -- and Spanish word names are starting to feel very right, so Canela has legs. It has a long history as a Latina first name, and Nell would be a great -- and easy -- nickname.

Many C forms of this name are becoming more popular, from Cassia for girls to Cassian, Cassius, and Caspian for boys, so Kass feels more possible today too. And Kassia and Kassiani are both intriguing longer forms.
