Name of “Henry”, son of “William Cottier” from Simon Perry in an email dated 13 December 2020 where he was trying to trace a DNA connection to his grandfather who had a son with Nola Gray:
https://nzolivers.com/tree/wc05/wc05_194.html

Simon is the great-grandson of Ernest Henry GRAY and Frances Maud ANDREWS. He is the grandson of their daughter, “Nola Ailsa Gray”.

This Mary Jane Grylls married “William Cottier” and Simon wondered whether one of their son’s “Henry Cottier”, (who had pubs in Inglewood), sons, “Eric” or “Cyril” could be his grandfather?

This theory for Simon Perry’s grandfather has since been discounted as at July 2022. Eric Cottier or Cyril Cottier is not Simon Perry’s grandfather. Please read later in this summary.

MR. HENRY WILLIAM COTTIER, Bandmaster of the Inglewood Brass Band, was born in the year 1868, in New Plymouth, where he was educated, and brought up to the soft goods trade, in connection with different firms. He afterwards gained experience in Wellington and other places in the colony, and in Sydney, New South Wales, and was for six years in business on his own account in New Plymouth. He has long been interested in musical matters, and was a member of the Invercargill Garrison Band, as leading cornet, a member of King's Band, at Wellington, and of the Wanganui Garrison Band. For a number of years Mr. Cottier was bandmaster of the New Plymouth Band.

MR. HENRY WILLIAM COTTIER was appointed Manager of the Drapery and Clothing Departments of the Moa Farmers' Union, Limited, in the year 1902. He is further referred to as bandmaster of the Inglewood Brass Band.

Daughter: Rita May Cowling Cottier
In a follow-up email dated 9 August 2022, Simon Perry wrote that, there is still a “Cottier” family connection. Simon’s new possible grandfather, “Edgar Lobb”, married a “Rita Cottier” in 1919. Edgar Lobb and Rita Cottier were the parents of D’arcy Baden Lobb.

Brian has found that this William's son, Henry William Cottier, had nine children, which not only included Eric and Cryil, but also a daughter called, "Rita May Cowling Cottier" who was born in 1899. Brian of nzolivers has yet to research if "Rita May Cowling Cottier" was the person who married “Edgar Lobb”, father of D’arcy Baden Lobb.
