Name and dates of birth and death from Muriel Leo’s (nee Oliver, 1917-1998) Family Tree.

Place of birth and place of death from Cynthia Glover (nee Coleman), whose great-great-grandfather was William Samuel Allen b.1843. (William's sister, Martha Allen, married Charles Oliver, this John’s mother and father).

Cynthia writes, buried with his parent’s Martha and Charlie [Charles] Oliver, Plot 31, Sec. 39, Row 8 (halfway along).

John is descendant from nobility on his mother's side (Martha nee Allen). Martha's paternal grandfather was Charles Stanhope, 3rd Earl Stanhope, descendant from a long line of families including Stanhope/de Ifferley/de Colleville/Crispin and Pitt.

John's x22 great-grandfather was William Crispin I, alias "Guillaume de Colleville", who was a companion of William the Conqueror at the Battle of Hastings in 1066. I recommend reading Cynthia Glover’s (nee Coleman) excellent book, “The Allen Family” (first published in 2005), complete with much excellent information and photos.

Copies of “The Allen Family” are held at:
- The Puke Ariki Museum-Library in New Plymouth, New Zealand
- Alexander Turnbull Library in Wellington, New Zealand
- The museum in Holdsworthy, Devon, England

In a telephone call on the 27 August 2021, Cynthia Glover advised Brian of nzolivers that copies for purchase, directly from her, are no longer available. There will not be another print run. Please see previous paragraph where copies are lodged.
