Is the female given name "Tatiana" originally Russian, or Greek?

[Sikeliot]

I think of it as Russian, but I've seen Greek women with it, too. Is it more like how Olga is a Slavic name used in Greece, or how Anastasia is a Greek name used in Slavic languages?

[Comte Arnau]

Latin.

Latin.

Then why isn't it common in Italy and Western Europe, but rather in Slavic countries and Greece?

[Merida]

Apparently it is a Slavic name of Latin origin, stemming from Tatius.

Perhaps it has something to do with orthodox sainthood, like with "Olga"

Because of Saint Tatiana being venerated in Orthodox countries.

It's very common in Argentina.

In Greece are Olga and Tatiana thought of as Russian names? Or are they established enough that Greeks do not see them as foreign names?

Never met a Tatiana in my life. Olga is pretty rare but I've seen it a couple of times.

Someone once told me both Olga and Tatiana are more common in old Pontic Greek women, and neither is common in anyone young.
