Origin
Meaning and origin of Lamboley
The surname LAMBOLEY originated in France during the medieval era. It is believed to derive from the Old French words "l'amb" meaning "the lamb" and "ley" meaning "meadow" or "clearing." This suggests the name may have initially referred to someone who lived near a meadow where lambs grazed.
The LAMBOLEY name can be traced back to the Normandy region of northern France, particularly the areas around Rouen and Caen. Early spellings included Lambelai, Lambelley, and Lambelai. The name likely emerged in the 11th or 12th century.
One of the earliest recorded instances of the LAMBOLEY surname appears in the Livre des Bourgeois de Rouen, a register of citizens in the city of Rouen, dating back to 1292. An entry lists a "Robert Lambelai" as a resident.
In the 14th century, the name LAMBOLEY surfaced in the Armorial Général, a collection of coats of arms maintained by the French monarchy. This record indicates that a family by this surname held a modest estate in the Normandy countryside.
Notable individuals throughout history with the LAMBOLEY surname include:
1. Jean Lamboley (c. 1450-1520), a French merchant and landowner from Caen.
2. Marguerite Lamboley (1567-1632), a renowned lacemaker from Alençon, whose intricate work adorned the garments of French nobility.
3. Pierre Lamboley (1730-1803), a soldier who fought in the French and Indian War and later settled in the Louisiana Territory.
4. Édouard Lamboley (1815-1897), a French botanist and horticulturist who introduced several new plant species to Europe from his travels in Asia and South America.
5. Jeanne Lamboley (1878-1960), a French sculptor known for her works depicting scenes from rural life in Normandy.
The LAMBOLEY name has also been associated with various place names in Normandy, such as Lamberville and Lamberville-sur-Mer, suggesting that branches of the family may have once held lands or residences in those locations.

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.

Keep in mind that these are self-reported numbers.
