Here are some suggestions for tennis players who may die soon (due to advanced age):
I don't think any of these are really famous names, but most were grand slam champions so will get obits.
- Bobbie Heine Miller: Born 04.12.1909, aged 104. Won the French doubles title in 1927 !!!
- Gardnar Mulloy: Born 22.11.1913, aged 100. Oldest living tennis HOF member.
- Dorothy Bundy Cheney: Born 01.09.1916, aged 97. Oldest living female Grand Slam singles champion.
- Thelma Coyne Long: Born 14.10.1918, aged 95.
- Welby Van Horn: Born 08.09.1920, aged 93.
- Pancho Segura: Born 20.06.1921, aged 92.
- Earl Cochell: Born 18.05.1922, aged 91. Only player barred for life by the US tennis association.
- Patricia Canning Todd: Born 22.07.1922, aged 91.
- Vic Seixas: Born 30.08.1923, aged 90. Oldest living male Grand Slam singles champion.
- Budge Patty: Born 11.02.1924, aged 90.
The players we generally think of as 'old' are not that advanced in years by today's standards (Rosewall, Laver, Court, King etc. are all in their 70s).
Welby Van Horn died in September but he only got an obituary in his local paper in Florida, not the national US paper (let alone a UK news source!)
