In 1837, Ballyconnell was a market and post-town, in the parish of Tomregan, barony of Tullaghagh, county of Cavan and province of Ulster. It was located (12.5 miles W by NW) from Cavan and sixty eight miles from Dublin and contained 453 inhabitants. This place had its origin in the English settlement in the time of James I when Captain Culme and Walter Talbot received 1500 acres, on which, at the time of the Pynnar's survey in 1619, was a strong bawn one hundred foot square and twelve foot high, with two flanking towers and a strong castle, three stories high, the whole occupying a site well adapted for the defence of the surrounding country.
