Monico Rivera Gautier - of Puerto Rico, USA - sadly passed away on c.17 Sep 2022 at the age of 109 years, c.99 days. He was born in Naguabo, Puerto Rico, USA on 10 June 1913. His paternal grandfather was born in Spain, and he had French ancestry on his mother's side. He was the oldest (known) living man in Puerto Rico at the time of his death, although his case wasn't known to us until late 2022.
While none of the posts by his granddaughter mention his full name, his first name was unusual enough that I was able to find his birth record just by searching for his first name in the birth index. Luckily, there happened to be a brief report mentioning his 100th birthday in 2013, so the match could be confirmed.
Rest in peace.
