LAPHAM Name Meaning and History
English: apparently a habitational name from a lost or unidentified place, possibly in Somerset or Wiltshire, where the surname is clustered, but perhaps a variant of Lopham, a habitational name from a place in Norfolk, so named from an Old English personal name Loppa + ham ‘homestead’.
