Teden by deed poll

In looking through all the births, marriages and deaths for England and Wales, I came across one which wouldn't tie in with anything else - the marriage in 1952 of Gladys Mary Teden to a Mr Lessels in Worthing. I couldn't find a birth of a Gladys Mary Teden, nor a marriage of a Mr Teden to a woman called Gladys.

Recently, I cracked this mystery - in 1948, Gladys changed her name by deed poll from Woodbridge to Teden (see the London Gazette archive). But I am still puzzled as to why she chose Teden as her new name; what was the significance?
