Semen Vorontsov (1744-1832). A participant in the Russo-Turkish War (1768-1774), he subsequently occupied diplomatic posts in Vienna and Venice before being appointed minister plenipotentiary (after 1796, ambassador) to the Court of St. James (1784-1806). He rarely returned to Russia, refusing Paul I's offers of appointment as vice-chancellorship and chancellor of the Empire. His son Mikhail was to become the governor-general of New Russia and viceroy of the Caucasus and his daughter Catherine married the IIth Earl of Pembroke. The street where he resided in St. John's Wood now bears his name (Woronzow [sic] Road) and he was buried in the Pembroke family vault in Marylebone.
