Beckford was twice married—first to Bridget, who died in 1691, and then again to Anne Ballard in 1696—and had two sons, the eldest of whom was also called
Peter. When he died from a
stroke on 3 April 1710, he was the wealthiest planter in Jamaica.
Charles Leslie claimed Beckford was "in possession of the largest property real and personal of any subject in Europe." This wealth was reputedly in the form of 20 Jamaican estates, 1500 slaves, and £1,500,000 in bank stock. His death resulted from an accident on 3 April 1710 when he rushed to the defence of his son, who had caused a commotion when the governor,
Thomas Handasyd, tried to dissolve the House of Assembly. Swords were drawn, and the elder Beckford allegedly fell down the stairs and died of a
stroke. Peter junior gave him a grandson,
William Beckford, generally known as "Alderman Beckford" and twice
Lord Mayor of London. He in turn produced the great grandson,
William Thomas Beckford, the writer and art collector. The latter had his great grandfather's portrait on display, according to Henry Venn Lansdown: :"That is the portrait of my great-grandfather, Colonel Peter Beckford. It was painted by a French artist, who went to Jamaica for the purpose, at the time he was Governor of the island. It is a full length portrait, large as life, the Colonel dressed in a scarlet coat embroidered richly with gold."
Petersfield in
Westmoreland Parish, Jamaica is named after him. ==Notes==
