If anyone has access to The Times archive, could they perhaps look in the issue of 21 June 1922 for the report on (and maybe a guest list from) the wedding the previous day of Leonora "Lorna" Stanley Baldwin, daughter of 'the' Stanley Baldwin, and Capt. Hon. Arthur Jared Palmer Howard, son of Margaret Baroness Strathcona, at St Margaret's, Westminster.
According to Kipling's Letters, the Kiplings were all present and Elsie was a bridesmaid. She subsequently accompanied the couple on their honeymoon to Colonsay, Argyll.
The Lord Lucan-alike in the doorway at the back bears more than a passing resemblance to the bridegroom's brother Donald Sterling Palmer Howard!

P.S. Stanley Baldwin and Kipling were cousins, and George Bambridge was a close family friend of the Baldwins, having served with Leonora's brother Oliver in the Irish Guards in WW1.
