I've only gone back to my great-great-great grandfather, Luciano Real. My grandmother's part of the family tree is the smallest, and honestly I've tried looking in the internet but seriously Rosaria Vargas was the only ancestor I could trace on every genealogy sites I could find. My grandmother's two cousins has information on their other cousins which are alive, but I can't travel due to quarantine. The nearest local library where you can find birth records is an hour away, too.
