Tony, Greetings from down under. (NZ) Sir Walter was my Grandmother's uncle and the information I have is accurate to two generations back. I am wanting to make the connection to Sir Redvers as my Grandmother stated that he was a cousin. Whether that was to her father or Grandfather I am unsure. As you would well know there is extensive information on his(Sir Redvers)side of the family.The Rev.James Buller wrote several books on early NZ but made little reference about his family. Please advise as to how I may assist.
