townland

noun

1. A geographical unit of land smaller than a parish.“Here is to be noted, that Sir Hugh got his estate by townlands, by reason of his agreement with Con O'Neil, whereas other undertakers of plantations in Ulster had several scopes of land (called proportions) admeasured to them, each containing one thousand acres, profitable for plough and good pasture, mountains and bog not reckoned in the number, but thrown in as an appurtenance.”
