Earl of Shelburne

It derives from Shelburne (Síol Bhroin), a region of County Wexford, Ireland.

On the same day that Lady Shelburne was elevated to the peerage, her eldest son by Sir William Petty, Charles Petty, was also raised to the Peerage of Ireland as Baron Shelburne.

In 1719 he was further honoured when he was made Viscount Dunkerron and Earl of Shelburne, also in the Peerage of Ireland.

The Petty estates were inherited by the late Earl's nephew, the Hon.

He assumed by Act of Parliament the surname of Petty on succeeding to his maternal uncle's estates in 1751[1] and the same year he was raised to the Peerage of Ireland as Baron Dunkeron and Viscount FitzMaurice.
