Thornham Family History
Thornham Surname Meaning
From Thorneholme in Burton Agnes (ER Yorks), which is recorded as Thurnum in 133, the place-name means ‘at the thorn trees’ from Old English þyrnum, dative plural of þyrne ‘thorn tree’.
From Thornham (Norfolk), Thornham Magna and Parva (Suffolk), or Thurnham (Kent), and perhaps other places similarly named, such as Thornham (Lancs).
These place-names derive from Old English þorn ‘thorn tree’ + hām ‘village homestead’ or hamm ‘enclosure water meadow’.
