Trebilcock Family History

Cornish: habitational name from Trebilcock in Roche (Cornwall). The placename is a rare post-1100 instance of a name derived from Cornish tre ‘estate farmstead’.

In this context, tre signifies a farmstead or an estate, which is a common element in place names throughout Cornwall.

The formation of the name combines this Cornish element with a Middle English surname based on pilcok ‘penis’.

Notably, there is a mutation of p to b that occurs after the feminine word tre, which reflects the linguistic evolution in the region.

This etymology highlights the unique blending of Cornish and Middle English influences in place names and surnames in Cornwall.
