VICTORIA (B.C.). Thursday.

The marriage was celebrated yesterday of Pamela only child of Mr and Mrs George Armstrong of Coombe Cottage, Coldstream, Victoria (Aust), to William Howard [sic] only son of the Hon Samuel Vestey and Mrs Vestey, of Stowell Park Gloucestershire, and Manchester Square, London, England, and grandson of Lord Vestey.

The ceremony was performed by Archdeacon Nunns at the Anglican church.

The State of Victoria was chosen for the wedding because it is a little bit of old England on the shores of the Pacific. The bride and bridegroom met in Australia when Mr Vestey visited the Commonwealth to inspect properties of his family.

The pretty bride wore a beautiful cream gown with a real lace collar and a full-length tulle veil and carried a bouquet of gardenias. 

After the wedding, 40 friends were entertained at luncheon. For her going-away frock Mrs Vestey chose a powder-blue suit with hat to match

The young couple left by steamer for Seattle whence they will proceed to Washington for a brief stay before they sail for England from New York probably late in October

Originally they planned to have the wedding in Melbourne later this year. The outbreak of war necessitated an alteration in the plans. The bridegroom obtained five weeks' leave of absence to come to Victoria for the ceremony.

He arrived back in Southampton with his 21-year-old bride on 23 October. They had two sons.

On 4 July 1940, William was gazetted from OCTU to be a Second Lieutenant in the 1st Battalion, Scots Guards. He was promoted Captain on 26 February 1942.
