Hammond Name Meaning
English (of Norman origin): from a personal name, Hamo(n), which is generally from a continental Germanic name Haimo, a short form of various compound names beginning with haim ‘home’, although it could also be from the Old Norse personal name Hámundr, composed of the elements hár ‘high’ + mund ‘protection’.
As an Irish name it is generally an importation from England, but has also been used to represent Hamill and, more rarely, McCammon.
Was it Hammond or Hammonds with an "S"? Who knows? It varied from generation to generation and from individual to individual. Probably confusion between singular and plural.
