At the time of Griffith's Valuation John K. Boswell held 2 townlands in the parish of Ballindoon, barony of Ballynahinch, county Galway, previously part of the Bunowen estate of the O'Neills. Robinson writes that he was one of the first persons to scientifically develop a fishery (in the Doohulla area) in Ireland and England and that he sold his Connemara property to W. Young in the early 1860s. In the 1850s a John Boswell also held 2 townlands in the parish of Killinvoy, barony of Athlone, county Roscommon.
