 Merrymount takes its name from the colony of Mare Mount, also known as Merry Mount or Merrymount.Colonist Thomas Morton wrote that the natives called the area "Passonagessit" and that the inhabitants translated this to "ma-re mount".The colony, established in 1625, was officially named Mount Wollaston by the Puritan separatists, but as Morton and other non-Puritans gained influence in the area, the name Merry Mount gained common use.
