Claris Family History
Claris Name Meaning
from the female personal name Clarice which has been regarded as a derivative of Clara but such a formation is difficult to explain. It may rather be from an abstract noun claritia based on Latin clarus ‘bright shining’ used as a personal name on the analogy of Lettice from laetitia ‘joy gladness’.
