Trezise

Tresise, sometimes spelled Tresize or Trezise, is a surname of Cornish origin.

The name could originate from any of several Cornish farms or hamlets such as Trezise in the parish of St Martin in Meneage, or Tresayes in the parish of Roche, both in West Cornwall. The derivation is from the pre-12th-century Cornish Tre-saws, meaning the place of the Saxons, a reference to English settlers in the county.
