"The marriage certificate has St Thomas Church Vestry. They are not married before the church altar. That would mean that one of the couple is not Catholic, and the priest would be ensure that it was recorded as such."
Hmm, interesting, I'd imagine Henry Murray wasn't Catholic, considering he's from an English family.
"I think that they have given Christchurch as "usual residence" because that is their intended residence. Eileen has not been in NZ before her marriage."
Christchurch as usual residence because that's where she intended to live certainly does make sense.
"Henry would be named for his father, and St Aubyn for mother's family"
Yep, makes sense.
"Stella would be named for maternal grandmother, paternal grandmother and mother"
John Murray, Frances Wilmot Coffin, John St Aubyn Burke, Stella Chester are all of Stella F E Murray's grandparents.
Bernard Percival Murray is my father; I do not know where his name comes from. I knew about my aunt and uncle. I will ask around the family.
Henry St. Aubyn Murray had a son, Anthony St Aubyn Murray. The St Aubyn name was not passed down to Anthony's children (probably lost all meaning by that point).
I will get a printout of the death record. Are there any other printouts in NZ that might be useful in finding further information about Eileen?
Thanks for all the help @wivenhoe
