Ms. Viorica Hogaș of Suceava, Romania sadly passed away on November 25, 2023 at the age of 108 years old.

She was the oldest living woman in Romania (the oldest living person is Mr. Ciocan).

Rest in peace, Ms. Hogaș.

The oldest known Romanian woman would now be Noja Paladia, born on 20 July 1915 in Alba?

RIP Viorica

Rest in eternal peace, Ms. Viorica Hogaș of Suceava in Romania !

While "only" 106, I still must mention Julianna Kolumbán (b. 26 February 1918), who's the oldest known living Székely (subgroup of Hungarians living mainly in Transylvania) person. 

She's been quite popular in Hungarian social media for years.

Best wishes to her!
