Zardeyn
Zardeyn is a surname of uncertain origin, possibly originating from the British Isles. Its etymology is unclear, with no definitive root in common English, Gaelic, or Welsh language origins. The rarity of the name suggests it may be a variant of a more common surname that has undergone phonetic or orthographic changes over time. Further research into genealogical records and historical surname databases would be required to establish a more concrete origin and meaning. The name is not widely documented and individuals bearing the surname are few in number, primarily residing in English-speaking countries.
