LANGDON is Anglo-Saxon derived from a Long (sand)dune or later a Long down(hill). England and southern Scotland have many of these hills often formed by sedimentary rock. Houses on these dons were called tons from which we ultimately get town. These settlements on the lang dons gave numerous Anglo Saxon place names Langdon and Langton, some with a prefix such as Dillington. See also Langton/Lenton project. Between the 5thC Anglo-Saxon settlement and the Norman invasion in 1066 there was plenty of time for these place names to corrupt.With the Norman conquest knights took the name of their land De Langdon. As a surname the name corrupted further to LANDON, LANGSTON(E), LUTON, LEYTON, LINDON, LINTON, LONGDON, LANGDOWN, LONGTON, LENTON even LONGSTAFF & LONGTHORN. In England LANGDON is the dominant form in the South & West, LANGTON in the North & West. LANDON and LANGSTON(E) developed later and occur in an arc around the Midlands. In USA the dominant forms are LANDON & LANGSTON. Many LANDONS and LANGSTONS in USA descend not from those names in GB but from LANGDON & LANGTON. If you have one of these names you come from a manor in England where your ancestor was the land owning Lord of the Manor. In some cases it is possible to identify the original settlement.Please consider taking a Y37 test to get your male line DNA.
