In 1854 Henry William Wilberforce, a brother of the Reverend Robert Wilberforce of Ballynakill parish, bought five townlands and islands in the parish of Inishbofin, barony of Ballynahinch, county Mayo, from the 3rd Marquess of Sligo. Following the sale Wilberforce took legal proceedings against the Marquess seeking compensation. In the 1870s Henry William Wilberforce of London owned 4378 acres in county Galway. 3141 acres of the estate were advertised for sale in the Landed Estates' Court in July 1874. The Irish Times reported on 6 July that negotiations on sums between £7000 and £9000 were on going. Cyril Allies was the purchaser and negotiations for the purchase of his estate by the Congested Districts' Board were taking place in the late 1900s. Inishbofin was originally part of county Mayo but was in county Galway by the 1870s.
