Arquivo P74 - Digby Estate Valuation and Survey

The Barons Digby of Geashill in the King's County derive their title from Lettice, the only daughter of Gerald, Lord Offaly, eldest son of the Earl of Kildare (1559-1580). Lettice married Sir Robert Digby of Coleshill, Warwickshire. He died in 1618 but Lettice, Lady Digby, then laid claim to the barony of Geashill and the estates of her grandfather, the Earl of Kildare, as heir general. The case was decided against her and in appeasement, James I created her Baroness of Offaly for life and awarded her the barony of Geashill. Her eldest son, Robert, was created Lord Digby of Geashill in the Peerage of Ireland in 1620. The title passed in direct descent until the death of Edward, 8th Baron Digby who died without issue in 1856. It was then passed to his cousin Edward St Vincent, 9th Baron Digby, from whom the present Lord Digby derives his title. In 1765, the 7th Baron Digby was also created 1st Baron Digby in the Peerage of Great Britain. In 1790, he was also created Viscount Coleshill and Earl Digby. The viscountcy and the earldom became extinct on the death of the 8th Baron in 1856, but both baronetcies (Baron Digby of Geashill in the King's County and Baron Digby of Sherbourne in the County of Dorset) continue to the present day.

He succeeded his father in the earldom in 1793. He served as Lord Lieutenant of Dorset for nearly fifty years, from 1808 to 1856. On 20 May 1824, he appointed himself Colonel of the Dorset Militia. He resigned the colonelcy at the beginning of 1846. He never married and on his death in May 1856, aged 83, the viscountcy and earldom became extinct. However, he was succeeded in the two baronies of Digby by his first cousin once removed Edward Digby, who became the 9th and 3rd Baron
