Where Duplessis' are most common

Historical parish links are strongest around No data. These are the places where the surname stands out most clearly in the older records.

The modern local-area list points to Southwark, West Berkshire, King's Lynn and West Norfolk, Waltham Forest and Wandsworth. Treat these as concentration signals, not proof that every family line began there.

Some modern areas include a three-digit suffix, such as Leeds 110. The suffix is a small-area code, so it stays in the table while the prose uses the plain place name.

Neighbourhood profile for Duplessis

Modern surname records can be compared with neighbourhood classifications. For Duplessis, this points to the kinds of places where the surname is most concentrated today.

These neighbourhood labels describe areas, not individual people. They are useful because surnames often cluster through family history, migration, housing patterns and local work. A surname can be strongest in one type of neighbourhood even when people with that name live across the country.

The UK classification gives the national picture. The London classification is more specific to the capital, where housing, age profile, tenure and population mix can look quite different from the rest of the UK.

Read profile summary

Group profile

These scattered, peripheral and often low residential density neighbourhoods house more workers in skilled trades and construction. Few households rent social housing and there are few students. Multiple car ownership is higher than the Supergroup average, perhaps because of poorer public transport connectivity. Incidence of mixed or multiple ethnicity is below the Supergroup average, and the absence of individuals identifying as Pakistani or Other Asian groups is also less pronounced. Flatted accommodation is less dominant than elsewhere in the Supergroup.

Wider London pattern

A Supergroup embodying London's diversity in many respects, apart from low numbers of residents identifying as of Bangladeshi, Indian, Pakistani or Other (non-Chinese) Asian ethnicity. There is lower than average prevalence of families with dependent children, while there are above average occurrences of never-married individuals and single-person households. The age distribution is skewed towards younger, single residents and couples without children, with many individuals identifying as of mixed or multiple ethnicity.

Meaning and origin of Duplessis

The surname DUPLESSIS originated in France during the Middle Ages. It is derived from the Old French term "du plessis", which translates to "of the manor house or enclosure". This suggests that the name was initially given to someone who lived near or owned a manorial residence surrounded by a fence or hedge.

DUPLESSIS is a locational surname, meaning it was originally taken from the name of a specific place. The earliest recorded instance of the name appears in the Domesday Book of 1086, which was a survey commissioned by William the Conqueror to record the landholdings in England after the Norman Conquest. This indicates that the name was likely brought to England from France during this period.

One of the earliest recorded individuals with the surname DUPLESSIS was Robert du Plessis, a Norman nobleman who fought alongside William the Conqueror at the Battle of Hastings in 1066. He was granted lands in Essex, England, as a reward for his service.

In the 13th century, a branch of the DUPLESSIS family settled in the Brittany region of northwestern France. One notable member was Armand Jean du Plessis, Duke of Richelieu (1585-1642), who served as the Chief Minister to King Louis XIII of France. He played a significant role in strengthening the power of the monarchy and centralizing the French state.

Another prominent figure with the DUPLESSIS surname was Jean du Plessis-Richelieu (1696-1788), a French Catholic cardinal and diplomat who served as the Secretary of State for Foreign Affairs under King Louis XV. He was instrumental in negotiating the Treaty of Paris in 1763, which ended the Seven Years' War between France and Britain.

In the 19th century, Edmond Rousseau du Plessis-Grénédan (1800-1865) was a French naval officer and explorer who participated in several expeditions to the Arctic regions. He also served as the Governor of French Guiana from 1855 to 1858.

One of the most notable individuals with the surname DUPLESSIS in modern times was Yvon Duplessi (1908-1976), a Canadian politician who served as the Premier of Quebec from 1936 to 1939 and again from 1944 to 1959. He was a strong proponent of Quebec nationalism and played a crucial role in shaping the province's political landscape.
