Cash, Johnny. February 26, 1932, 7:30 AM CST, Kingsland, AR (A).
Segara, Helene. February 26, 1971, 10:08 AM CET, La Seyne, France (AA).

OTHER:
Sturgeon, Theodore. February 26, 1919, 8:30 PM, New York, NY (AA).

I have swapped Cash in for Sturgeon. I kinda hate doing this because I love Sturgeon's work (I read a lot in the '60s) and think his social impact was huge (though barely seen at the time).

Nonetheless, Cash's name will be remembered longer, though I'm sure Sturgeon will remain researchable in 100 years). The substitution furthers my goal of a list that will mostly be recognized and that will be entirely researchable in a century.
