The name of Nisi was forgotten when Gaelic Ireland collapsed in the 17th century. Irish nobles had their estates confiscated in the plantations of Leitrim. The English incorporated Moynish into the barony of Leitrim and Cromwellian forces plundered Moynish in 1652. Though forgotten today, the place name of Moynish is preserved by the Irish annals and English Fiants.
