The Guinness World Records rejected her longevity claim based on lack of evidence, while promoters made strongly worded demands that the claim be accepted on its evidence. The longevity claim was supported by the highest ranks of the government of her native Dominica. The observed life expectancy on Dominica, and the extremely high death rates among supercentenarians, were cited as requiring greater evidence than her promoters provided. The baptismal register was a third-generation copy; the entry cited was for "Elizabeth Israel", her married name; and no documents attesting to the birthdate and dating to the first century of her stated lifespan were ever produced.
From February 1991 to her death, Israel claimed to be older than the "validated world's oldest person", though this was not publicized until December 1999. Israel had memories of the early 20th century and was believed to be probably at least 100 upon her death in Dominica in 2003.

@ale76 thank you Ale! I had been very curious about her case after finding that the GRG once considered her case to be believable. The GRG should update their 2015 list. Anyway, I hope you're doing alright;)
