From Brian (of nzolivers.com) trip to New Plymouth February 2009, the Headstone at Te Henui Cemetery, New Plymouth, New Zealand (next to James and Ruth’s grave):
In Loving Memory of Matilda Robins

At Rest

Brian (of nzolivers.com) questions the year of birth. William would have been very young when he married and had his first child. It is more likely he was born in 1836.
