Meaning of the Name
Senuna was a Celtic Goddess worshipped in Roman Britain about 1700 years ago. Her name appears in various forms on the votive plaques, namely Senuna, Sena and Senua, that were discovered 2002 in an excavation. Conceivably it might be related to the Proto-Celtic *seno- ‘old’.
She may have been a water Goddess local to the region. Perhaps she presided over a sacred spring or was a river diva. A sort of local Minerva.
Supplicants also offered exquisite representations of the goddess Victory, with laurel wreath in hand and foot firmly on the world she might help them rule.
The name Senua was possibly wrongly attributed by River Senua mentioned in the Ravenna Cosmography, a kind of gazzeteer created around 700 AD, some 350 years after the date of the offerings now on show.
Female form of Elias. A female given name found in Assyrian/Akkadian, אֱלִיעָנָה (Hebrew), Ηλιάνα (Greek), إليانا (Arabic) and in Italian, Portuguese and Spanish
Literally it translates from Hebrew as "My God has answered me." (El- [God] elohe-Israel [Eli, the God of the Patriarch Israel]" (Genesis 33:20).), and from Italian and Greek as "Sól" or "Daughter of Sól."
Mari is the Scandinavian alteration to Mary, mother of God, or Maria, which is her mother's middle name. It is a hidden reference to the ocean, maré- or -i in some languages (therefore another reason for the name not ending in "ie") and other disambiguation.
The name may have originated from the Egyptian language; it is likely derivative of the root mr "love; beloved"  (compare mry.t-ymn "Merit-Amun", i.e. "beloved of Amun").
