Merewynn is English, Welsh in Origin.

Merewynn is an Anglo-Saxon feminine name analyzed from Old English elements mere “sea, lake” and wynn “joy, delight,” giving the luminous meaning “joy of the sea.” Medieval spellings often blurred -wynn and -wine, so you may also encounter forms influenced by wine “friend,” yielding a parallel reading “sea-friend.” Both interpretations fit early English name-building patterns and sit alongside cognate formations like Godwynn/Godwine.

Use is documented in late Anglo-Saxon England; the 10th‑century abbess Saint Merwenna/Merwinna of Romsey reflects the name cluster’s presence before it waned after the Norman Conquest. The modern form was revived in antiquarian circles and gained a gentle boost through literature, notably Anya Seton’s Avalon, which used the spelling Merewyn. Variants include Merewyn, Merwynn, Merewenna, Merwenna, and Merwinna; related names are Morwenna (Cornish/Welsh) and the masculine Merwin, Mervyn, and Merewine. Suitable diminutives include Wyn, Winnie, and Mere.
