She was the last known person to speak Bo and was 85 years old.
Survival International says the;
"Bo are thought to have lived in the Andaman Islands for as much as 65,000 years, making them the descendants of one of the oldest human cultures on Earth."There are other Great Andamanese tribes but the total number of survivors is only 52.
Britain colonized the Andaman Islands in 1858 and the decimation of the Andamese tribes ensued.
A tragic story.
May the God/Great Spirit rest the soul of Bo Sr until that day.
