Officials from the Guiness World Book of Records are checking the passport and birth documentation of a Montreal-area woman – who may be the world’s oldest person.

Cecilia Laurent is believed to have turned 120 on Sunday.

She moved to Quebec from Haiti in 2010 – after that country’s devastating earthquake – and lives in Laval with her family, including her 28-year-old great-grandson Ronald Chery.

He says Guinness employees are currently on a fact-finding mission in Haiti to confirm the date of Laurent’s birth – which her family maintains is January 31st, 1896.

Chery says only three of Laurent’s 12 children are still alive – and the eldest is in her 80’s.

He says his phone rings often and he hears from people across the country who want to speak to Laurent and “find out the secret” to longevity.

Chery says Laurent’s answer is God – and she prays for several hours consecutively, every Friday.

He adds that “all-natural” food – and watching cartoons – have also helped his great-granny stay healthy.
