LeClaire, Le Clerc, Leclerc, Leclair, Le Clair and Licklär: The Documented Surname Variants
Summary
The House of LeClaire is recorded under eight spellings across more than six centuries: Le Clerc, Le Claire, Le Clerc, Leclerc, Leclair, Le Clair, Licklär, and the emerging Greenland-LeClaire identity. Each is a recorded rendering of the same documented family, beginning with Mengin (Moingins) Le Clerc of Lorraine, born c. 1310 and first named in a surviving 1355 charter. As the family moved from Lorraine into the Rhineland and Palatinate, and later into England, each region's scribes, priests and civil officers wrote the name in the form natural to their own language. This page consolidates every variant into a single record and distinguishes this armigerous Lorraine house from unrelated, non-armigerous Canadian and Franco-American Leclerc and Leclair families.
What is the connection between LeClaire, Le Clerc and Leclerc?
LeClaire, Le Clerc and Leclerc are recorded spellings of a single documented surname borne by one family across six centuries: Le Clerc is the medieval Lorraine form first recorded in 1355, Leclerc the standardised early-modern French form, and LeClaire the modern English form adopted from the eighteenth century onward. Each spelling change is attested in charters, letters patent and parish or civil registers rather than inferred.
Le Clerc
c. 1310 – 17th century · Lorraine, France
The earliest documented spelling of the House. Borne by Mengin (Moingins) Le Clerc of Lorraine and his direct descendants, including Colin Le Clerc and Jehan Leclerc de Pulligny, ennobled in 1464. Documentary evidence: the 1355 act of sale of inherited lands at Folz, and the 1464 letters patent of nobility of the Duke of Lorraine.
Le Claire
18th – 19th century · England, France
The Anglicised two-word spelling adopted as the family established itself in Britain from the eighteenth century onward, a transitional form between the French Leclerc and the modern one-word LeClaire. Documentary evidence: English parish and civil registers of the eighteenth and nineteenth centuries.
Le Clerc de Pulligny
1464 – 1650 · Pulligny and Xirocourt, Duchy of Lorraine
The seigneurial title taken from the seigneury of Pulligny, south of Nancy, borne by the ennobled branch of the family. Recorded bearers include Jehan Leclerc de Pulligny and Claude Leclerc de Pulligny. Documentary evidence: the 1464 letters patent of nobility and the 1623 restoration of hereditary nobility to the brothers Jean and Alexandre Le Clerc.
Leclerc
16th century – present · France (nationwide)
The standardised modern French one-word spelling, in use from the Renaissance onward and still the most common form of the surname in France today. Documentary evidence: sixteenth- and seventeenth-century civic, ecclesiastical and notarial records of Lorraine and France.
Leclair
17th century – present · France
A one-word French variant recorded within this lineage's French documentation. Documentary evidence: seventeenth- and eighteenth-century French civil and parish records.
Le Clair
16th – 19th century · Lorraine, Rhineland
A transitional spelling recorded during the family's eastward movement from Lorraine into the Rhineland — a phonetic softening of Le Clerc. Documentary evidence: Rhenish and Palatine parish registers of the seventeenth and eighteenth centuries.
Licklär
17th – 19th century · Rhineland, Palatinate, Germany
The Germanised phonetic rendering used by the Rhineland branch of the family, recording how the French Le Clerc sounded to German ears after generations east of the Rhine. Recorded bearer: Monika Ute Licklär. Documentary evidence: Palatine and Rhineland parish and civil registers of the seventeenth to nineteenth centuries.
Greenland-LeClaire
2026 – present · England
The modern joint identity formed by the 22 May 2026 marriage of Brandon Noble LeClaire, present head of the House, and Abigail Jane Greenland-Pigott, uniting the documented LeClaire inheritance with the maternal Greenland line. Documentary evidence: the 2026 marriage record and modern civil registers of the Greenland and Pigott families.
A note on unrelated families of similar name
This armigerous house of Lorraine, Rhineland and English descent is distinct from unrelated Canadian and Franco-American Leclerc and Leclair families, found chiefly in Québec, Ontario and Louisiana. Those families share only the spelling of the surname, are not armigerous, bear no recorded coat of arms, and have no documented genealogical connection to the House of LeClaire recorded in this archive.
