Legal agreements in the form of deeds and indentures relating to the Derenzy family’s title and interest in lands in the vicinity of Tinnycross, County Offaly. The earliest deed dating from 1630, records Sir Mathew de Renzi purchasing the townlands of Ballynashragh, Ballycosny, Tyrenehinan, Kilmore and Derry, all in the barony of Ballycowen, on behalf of his son Mathew DeRenzy, then at the bar in London. The vendor was Robert Branthwaite of London, who had been granted the land by letters patent of King James I. Further adjoining townlands of Rossnagouloge or Cappanure were purchased by Sir Mathew from Allen Jones in 1630, and the following year the adjacent townlands of Derrykilliagh and Kilbeg were purchased from Art McOwen O’Molloy. All were settled on his son, Mathew DeRenzy.
The bulk of the collection consists of numerous leases and mortgages raised against the land by Mathew DeRenzy between 1699 and 1703, while he lived at Cloghbemon in County Wexford. Later items in the collection relate to the sale of the lands to Reverend James Cox, Archdeacon of Ferns.
