Cha
A rare surname of uncertain origin, possibly a short form or an abbreviation-like survival rather than a standard medieval English family name.
The #3,654 most common surname in the United States (2010 Census) — about 1 in every 31,725 Americans shares it.
Etymology
The historical evidence for Cha as a surname is thin. One 19th-century surname dictionary lists it only tentatively and suggests it may be connected with Sees or Sées, a town in Normandy, which would make it a locational name of French origin. Because the record is brief and uncertain, it is safest to treat the name as having an unclear or possibly continental source rather than a firmly established English derivation.
History
Cha is uncommon in English-language records and does not appear to have a large medieval pedigree in the standard surname books. The few dictionary traces suggest a French or Norman connection, but the evidence is too slight to reconstruct a clear family history. In modern use, the surname is rare and may also reflect later immigration or simplified spelling.

Fun fact
Lower’s old dictionary treats the name as a very tentative possibility, which is a reminder that some surnames entered the record only in fragmentary, hard-to-classify forms.
