The couple were in South Africa in the 1920.'s according to this account I copied
Lunch at Clarence House, 3rd July 1922, account by William Howard Taft, former US President.
"The Duke [of Connaught] lives at Clarence House, a very pleasant home I should judge, and he had with him at the time his daughter Patricia and her husband Captain Ramsey, for she married a commoner, as well as his daughter-in-law, Princess Arthur of Connaught. Her husband, the Duke’s son, is the Governor General of South Africa, and she had just returned from there, leaving her husband on duty. Earl Balfour, Lord Desborough, the active men of the Pilgrims, Mr and Mrs Rudyard Kipling, Winston Churchill and his wife, and an aide who had accompanied Princess Arthur from South Africa were also there. The Earl of Cavan, who is now the Chief of Staff of the British Army, and possibly one or two others, whose names I have forgotten, were also members of the party."

3 Lady Patricia Ramsey (formerly Princess Patricia of Connaught, daughter of Duke)
4 Prince Arthur, Duke of Connaught and Strathearn, son of Victoria, masonic Grand Master
