In 1926 who was the duke and duchess of york?

When H.R.H. The Prince Albert, Duke of York succeeded to the throne of the United Kingdom in 1936, he took the name HM King George VI, and his York title merged with the Crown. This meant that his former title Duke of York and Duchess of York went "back into the pot" of properties, lands, and titles that the king or his heirs might choose to one day bestow on another member of the family.

But custom, the title Duke of York is bestowed on the sovereign's son, specifically, the second eldest son, and this usually when not until he attains the age of majority. King George VI had two daughters - Princess Elizabeth, born 1926, his heiress, and Princess Margaret, born 1930 - but no sons. Elizabeth succeeded her father as sovereing in 1952 at the age of 25. During the year 1961, H.R.H. The Prince Andrew, the second son of Queen Elizabeth and her husband, was less than two years of age; although he was destined for that title, it was not until 1986 that the Queen bestowed it on him.

In a sense, then, it might be said that the duke of York in 1961 was the Queen.
