There was a shooting party at Luton Hoo in early December 1891. Mr de Falbe, the resident (owner?) was the Danish Minister to Britain and thus had contacts with the Princess of Wales and other members of the royal family. May and her family had visited there many times before and it was a popular destination in the summer for tennis parties and casual get-togethers. In the Dec 1891 party, Eddy was part of the gathering--most likely to facillitate the proposal since it was heavily gossiped-about in the family. The day following their arrival, Eddy proposed after dinner. They next day they telegraphed relatives and Eddy went shooting and played cards together that night. The day after that, they were photographed and Eddy left for London to notify his parents in person (though they'd been telegraphed and responded) as well as receive the sanction from QV. Once it had all seemed 'in the bag', Eddy seems to have jumped the gun a bit since some relatives apparently didn't expect the news quite so quickly and the news had begun to leak out.
The Falbes took a photo of the boudoir that Eddy proposed in and sent it to QM who pasted it in her photo albums--I really wish there was another publication of her albums, the one published had so few early photos. In 1918, QM, GV and some others visited Lady Wernher's convalescent home for officers which was located at Luton Hoo. QM noted that it was the first time she'd been there since her engagement 27 years prior. She noted that the house was so altered that it was 'difficult to make out where the former rooms were'.
