Caitlyn's paternal grandmother was Bertha Mary Yarn, born and raised in Harbour Breton, Fortune Bay. At age 20, in 1901, she was listed in census documents as a patient at Victoria General Hospital in Halifax, where her occupation is noted as "housework." Bertha later married Hugh Burton Jenner of New Brunswick, and they had three children, including Caitlyn's father Bill, before immigrating to Massachusetts in 1925. Bertha died in Michigan in 1980.
"Bill had been born in the city of St. John's, Newfoundland and Labrador," Caitlyn writes of her father in her memoir, "Secrets of My Life," released this past spring. Archival documents show Bill had actually been born in St. John, New Brunswick.
Like Caitlyn, Bill was a champion runner: he competed in the U.S. Army Olympics in Germany in 1945, winning the silver medal in the 100-metre dash. An arborist, he died in California in 2000.
Caitlyn, 67, won a gold medal in decathlon in the 1976 Montreal Olympics. Openly transgender, she starred in "I Am Cait," a reality TV show focused on her transition, last year.
When it comes to TV, Caitlyn is best known for appearing on "Keeping Up With the Kardashians," on which she has starred with ex-wife Kris Jenner, daughters Kylie and Kendall Jenner, and stepchildren Kim, Kourtney, Khloe and Rob Kardashian since 2007.
Caitlyn's other children are Burt, Brandon and Brody Jenner and Casey Marino.
