Morning all.
After a lot of searching in an area of NZ I am not familiar with, the attached illustration, along with actual allotment measurements [prior to resurvey done to include the roading provision easements that can be found in the WELLINGTON INDEPENDENT adverts that ran from late December 1871 into January 1872 page 3] gives a partial answer to Ashley and his quest to match up oral family history with records of the period, that can be found in various archives.
Search using POHATU spelling.
As assumed in the little plan initially supplied, the POWHATU West survey as illustrated, shows allotments of 3 to 7 of the survey that saw the land being broken up, and sold by the original Crown grantees.
AND the POWHATU WEST allotments of 1 & 2 having undergone further survey and being re numbered 1, 2 & 3, of former 1 & 2. Unfortunately none of the allotments so far identified are of 10 to 12 acres.
Named title holders: J BAIRD, C COTTLE, J TULLY, Mrs E JONES wife of WPH JONES
E & O E Alan.
