Married to the third King of Bhutan, Jigme Dorji Wangchuck (marries 5 Oct 1951). Daughter of Sonam Topgay Dorji & Mayum Choying Wangmo.

1972 the Third King's health had seriously deteriorated. On 22 April 1972 Kesang Choden was formally appointed regent to act on his behalf during his illness — one of the very few women in Bhutanese history to hold such a position.

From 1972 her title shifted from Queen Consort to Queen Mother, in Dzongkha Gyalyum (རྒྱལ་ཡུམ). She did not remarry. During the Fourth King's long reign (1972–2006) she remained a senior figure at court but kept a deliberately low public profile compared with her four daughters-in-law — four sisters from the Yangtse-based Ngalop family who married her son in a single ceremony in 1988. Observers describe her role in this period as that of a private matriarch rather than a public figurehead, focused on religious practice, family, and the education of her grandchildren.

When her son Jigme Singye Wangchuck abdicated in December 2006 in favour of his eldest son, Kesang Choden's formal title became Gyalyum Chenmo — "Great Royal Grandmother" — though in common Bhutanese usage she is simply the Royal Grandmother.
