There have been four baronetcies created for members of the Thorold (pronounced "Thurrald", though the late Revd. Henry Croyland Thorold was insistent on the pronunciation "Thorough") family of Lincolnshire, two in the Baronetage of England and two in the Baronetage of Great Britain. As of 2014 one creation is extant.
The Thorold Baronetcy, of Marston in the County of Lincoln, was created in the Baronetage of England on 24 August 1642 for William Thorold. He fought as a Royalist in the Civil War and represented Grantham in the House of Commons after the Restoration. The fourth Baronet sat as Member of Parliament for Grantham and Lincolnshire. The ninth Baronet was Member of Parliament for Lincolnshire. The tenth Baronet was a noted book collector. The twelfth Baronet represented Grantham in Parliament. The fifteenth Baronet was a Captain in the Royal Navy and leader of the Lincolnshire County Council. As of 28 February 2014 the present Baronet has not successfully proven his succession and is therefore not on the Official Roll of the Baronetage, with the baronetcy considered dormant since 1999.
Thorold (2011 population 17,931) is a city in Ontario, Canada, located on the Niagara Escarpment. It is also the seat of the Regional Municipality of Niagara.
The Welland Canal passes through the heart of the city, and the Twin Flight Locks, located downtown, attract thousands of tourists annually.
The first survey of Thorold, or Township 9 as it was known then, occurred in 1788. The earliest communities in what is now Thorold emerged at Beaverdams, DeCew Falls and St. Johns but, after the opening of the First Welland Canal in 1829, they were superseded by the new canal villages of Thorold, Allanburg and Port Robinson. Thorold, located on the brow of the Niagara Escarpment, soon became dominant and was incorporated as a village in 1850 and as a town in 1870. When the Regional Municipality of Niagara was formed in 1970, the Town of Thorold expanded to include the former Thorold Township. In 1975 the town became incorporated as the City of Thorold.
Thorold is also the location of the War of 1812 battle site, Beaverdams, where, on June 25, 1813, Colonel Charles Boerstler and his American troops were defeated by a force of 80 British regulars and 300 Caughnawaga Mohawks.
