The will of Thomazin Moyse of Otterham, dated 19 October 1734, mentions her husband John Moyse, her sisters Elener Trethouan and Rebeckah Trethouan and her father William Trethouan. The witnesses were Edmund Turner and Thomazin Trethouan.[1]


There was a William Trethowan baptised at Mylor in 1678, son of John and Eleanor, who could be the William who married Thomasine Turner. Further research would be necessary on this point.


Thomasine (Turner) Trethouan may be the Thomasine Turner baptised at Poundstock in 1679, daughter of Richard and Mary. There was also a Thomasine Turner baptised at St Gennys in 1687, daughter of Thomas, but that would be rather late for an individual married in 1702/03.

As Rebecca (Trethouan) Holman, who lived at Warbstow, is known from her probate documents to have died between Aug and Dec 1771, and no burial record has been located for her elsewhere, it appears that the name Thomasin in the register is an error for Rebecca.
