Etymonline
Word Origin & History
Lambert
masc. proper name, from Fr., from Ger. Lambert, from O.H.G. Lambreht, from lant "land" + beraht "bright." O.E. cognate was Landbeorht. The popularity of the name from 12c. is probably due to immigration from Flanders, where St. Lambert of Maestricht was highly venerated. Attested as a surname from 1142.
