Hi Philadelphia,
I checked his NZ arrival.
Name: Thomas B Pinney
Event Type: Immigration
Event Date: 20 Aug 1873
Event Place: Canterbury, New Zealand
Gender: Male
Marital Status: Married
Nationality: England
Age: 37
Ellen PINNEY, Age 28
Sam: PINNEY, Age 10.
https://familysearch.org/ark:/61903/1:1:FST8-CTBI can see on Samuel PINNEY's marriage that it is indexed as PENNY, in 1886.
5289/1886 PENNY SAMUEL BARRETT FANNY COOTAMUNDRA
So, I will check BDM's under the name of PENNY, and see how I go.
Mary
