Peter and Henrietta Barfoot were major lessors of property in the barony of Aran at the time of Griffith's Valuation. Peter Barfoot is recorded as the proprietor of over 11,000 acres in county Galway in the 1870s. This represents much of Aran Islands estate of the Digby family as Peter Barfoot was married to Henrietta Digby. The Barfoot's only child Henrietta married in 1851 Thomas St Lawrence 3rd Earl of Howth and a daughter of this marriage married Captain Benjamin Lee Guinness, brother of Baron Ardilaun. The St Lawrence and Guinness interest in the Aran Islands was sold to the Congested Districts Board circa 1915.
