Florence Bjelke-Petersen · Wikipedia (en)
For “Title (Lady Bjelke-Petersen)” 1984 of Florence Isabel Gilmour
"When Joh Bjelke-Petersen was knighted in 1984, Flo Bjelke-Petersen became Lady Bjelke-Petersen, and was officially known as \"Senator Lady Bjelke-Petersen\". She was frequently referred to as \"Lady Florence\" or \"Lady Flo\"."
A courtesy style, not an honour in her own right. The Parliamentary Handbook lists her display name as "BJELKE-PETERSEN, Lady Florence Isabel", confirming the official usage.
