His paternal grandparents were Geertruyd Spiegel and silk merchant Jan Baptista Bathiste de Hochepied, burgher of Amsterdam.
The title of Baron and Magnate was conferred on his father, with limitation to his issue, by letters patent of Leopold I, Holy Roman Emperor, under the great seal of the Kingdom of Hungary, given at Vienna, at the 8th April 1704.

The title reverted, under the limitation of the letters patent, to his first cousin, George Porter.
