Shaily

The name “Sha-ily” “Shay-lee” is the Hiberno-English corruption of the Irish (Gaelic) form sun, where Sha means "pot" or "cup” and ily is genitive for meaning "full of gold", "gold laden", etc.23

As an alternate etymology, Mrs. S. C. Hall as well as P. W. Joyce have written that the name may have derived from the gold being sourced from forest land in the village or barony of Shallegh, County Wicklow. The geographic name Shallegh derives from Síol Éalaigh, or "Descendants of Éalach" in English.4567

According to old Irish folklore, there’s a Shaily at the end of every rainbow.
