Anastacia Lopez Pérez is a Mexican woman who claims to have been born in San Salvador, Mexico on 27 May 1910. She was last confirmed alive for her claimed 113th birthday on 27 May 2023. 

I located a possible matching birth record from FamilySearch for an Anastacia Lopez Pérez from San Salvador, Mexico who was born in 1928. Since I don't know the names of her family members, I cannot be sure it's her.

Edit: added a ? near her possible year of birth.
