Jenna The name is a diminutive of the first name Jennifer. The terms and Gwen hwyfar forming the old name Gwenhwyfar mean "pure" respectively and "soft". Jenna is an independent woman, a true lioness who fully supports. Devoted to her work, she does not grant apparently little interest in her emotional life. But do not rely on this stiff gait because it conceals a deeply sentimental and loving soul. It's up to you to discover its true nature: fragile, poetic and endearing.
