Maris Clesiu also known as Marius O. Clesiu and Octavian Clesiu was born Aug 15, 1943 as per US Public Records Index.
Addresses were listed as George St. Flusing Queens, NY and another listed just as Ridgewood, NY .
My research could not uncover any additional information. Although I did find two additional people with the same surname I could not connect them to this individual.
There was a clue with one of these other individual's that there might be another surname connected to this surname. That surname was Cleski but could not find any connection.
I feel confident that I've at least given this person back their birth date.
Rest in peace. You have been remembered.
