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.

Meaning and origin of Sebastiao

The surname SEBASTIAO originated in Portugal and can be traced back to the medieval period. It is derived from the ancient Greek name "Sebastianos," which means "venerable" or "revered." The name was brought to Portugal during the Roman occupation and later became associated with Saint Sebastian, a popular saint in the region.

One of the earliest recorded instances of the surname SEBASTIAO can be found in the Inquirições de Afonso III, a 13th-century Portuguese legal document that recorded property ownership and taxation information. The name was also present in various monastic records and parish registers from that time period.

In the 15th century, during the Age of Discovery, many Portuguese explorers and navigators bore the surname SEBASTIAO. One notable figure was João Sebastião, a navigator who accompanied Vasco da Gama on his historic voyage to India in 1497-1499.

The name SEBASTIAO was particularly prominent during the reign of King Sebastian I of Portugal (1554-1578). King Sebastian's tragic disappearance at the Battle of Alcácer Quibir in 1578 gave rise to the legend of the "Sebastianismo," a belief that the king would one day return to reclaim his throne.

Another notable bearer of the surname SEBASTIAO was Sebastião José de Carvalho e Melo, 1st Marquis of Pombal (1699-1782). He served as the Prime Minister of Portugal during the reign of King Joseph I and was known for his ambitious program of reforms and policies aimed at modernizing the country.

In the 19th century, Sebastião Saldanha da Gama (1839-1880) was a prominent Portuguese naval officer and explorer. He led several expeditions to the interior of Angola and made significant contributions to the mapping and exploration of the region.

Today, the surname SEBASTIAO is widely distributed throughout Portugal and its former colonies, particularly in Brazil, where it has been adopted by many families over the centuries.
