Hi BGM,
The 1987 death record discovered by Janette provided a date of birth of 14 January 1916, and if this relates to the right person the Irene RICKARD born 1917 may not be her.
And KHP, you said above that "Stanel and Margaret were living in Manawatu-Wanganui according to the Electoral Rolls."
Can you provide a date for this Electoral Roll entry? The Irene May REES who died in 1987 at Dunedin was a widow. She could have moved south after Stanel's death in 1955.
We need to find a record of her birth, and marriage to Stanel.
