Pett Family of Wales

I am researching the Pett family in South Wales. Have tracked part of the family to Liverpool, but there are Ford-Carey in South Africa that may be related to the Pett family in South Wales.

The Pett Family that I am researching were in the Toxteth area in 1889, but are believed to have gone there from Cornwall.

In addition I am also trying to track the Gill family, last known location at Frithel Stock Stone in North Devon
