\Sur"name`\, n. [Pref. sur + name; really a substitution
for OE. sournoun, from F. surnom. See {Sur-}, and {Noun},
{Name}.]
1. A name or appellation which is added to, or over and
   above, the baptismal or Christian name, and becomes a
   family name.
Note: Surnames originally designated occupation, estate,
      place of residence, or some particular thing or event
      that related to the person; thus, Edmund Ironsides;
      Robert Smith, or the smith; William Turner. Surnames
      are often also patronymics; as, John Johnson.
2. An appellation added to the original name; an agnomen.
   ``My surname, Coriolanus.'' --Shak.
Note: This word has been sometimes written sirname, as if it
      signified sire-name, or the name derived from one's
      father.
