When did Irene Hunt die?I have gotten multiple answers, and I can't tell which is right.

According to most sources, Irene
Hunt (1907-2001), the author of Across Five Aprils, died on
her 94th birthday in 2001. However, I have found several conflicting dates and locations. Most
dates state her birthday (and date of death) as May 18; another source claimed it to be May 8
(which could be a typographical error). Yet another source, quoting her younger brother, Loren
"Joe" Poe, claims that Hunt's birth records were altered to avoid mandatory retirement from the
Illinois school system; he claims she was born on May 14, 1902, which would have made her 99
years old at the time of her death. Several sources claim she died in Champaign, Illinois;
another source calls the location as Savoy, Illinois (a small town near Champaign), where she was
living in a nursing home. After teaching in Illinois public schools and then at the University of
South Dakota, she retired in 1969 to devote her life full-time to writing. She apparently lived
in Florida for a while before her death.
