Unknown old FIDE players I am interested in the History of chess and looking at old FIDE ranking lists I am a bit puzzled by the lack of information about some very good players.

For instance, in the list of July 1972:


Shmit, from Soviet Union, and ranked #95 in the world with 2480 Elo https://www.olimpbase.org/Elo/player/Shmit.html
Zurakov, from Soviet Union, and ranked #275 in the world with 2415 Elo

Abaharov, from Soviet Union, and ranked #285 in the world with 2410 Elo

Does anyone know them?

I am also looking to know more about a player called Donnelly, from Ireland, and ranked #416 in 1970 with FIDE rating of 2240 (a very decent rating at that time!)

I found one in Big Database 2016.  Anatoly Shmit, born 1941 in Latvia, with 157 games between 1959 and 1989, all played within the USSR.  Many strong Soviet players never got the chance to play outside the Soviet Union, and Shmit does not seem to have ever been awarded a FIDE title, although he was undoubtedly a very strong player, having beaten a number of well known players including Mikhail Tal.

According to chessgames.com, his name was more accurately Anatolijs Šmits.  He won the Soviet Junior Championship in 1960, and was Latvian Champion in 1969 and 1975.  He died in 1998, aged 56.
