Another great-grandmother, Cornelia Louisa Intveld, married in 1822 to Royal Navy officer and merchant, William Purvis, from Dalgety Bay, Scotland, and a first cousin of American abolitionist Robert Purvis; a noted fine soprano and a beauty of her era. Upon glimpsing her across the auditorium at the opera in London, England, British King William IV sent his equerry to invite her to his box. After she refused, the King sent the equerry back just to ask her name. Intveld was born in Padang, West Sumatra, Indonesia, where her father, who came from humble beginnings in Hellevoetsluis, South Holland, rose up through the Dutch East India Company to become the Dutch Resident of Padang. Her maternal grandmother was an Ono Niha "ranee" (a term covering every rank from chieftain's daughter to princess) married a prominent Dutch colonial official and merchant. Acclaimed British harpsichordist, Violet Gordon-Woodhouse, and Hawaiian settler, Edward William Purvis, according to popular belief, was the namesake of the ukulele, are Margaret Trudeau's first cousins, three times-removed. Trudeau explored her mother's family's roots in Singapore during an episode of "Who Do You Think You Are?".
