ellauri142.html on line 77: The Tolstoys were a well-known family of old Russian nobility who traced their ancestry to a mythical nobleman named Indris described by Pyotr Tolstoy as arriving "from Nemec, from the lands of Caesar" (Lithuania, from the sound of it) to Chernigov in 1353 along with his two sons Litvinos (or Litvonis) and Zimonten (or Zigmont) and a dozen or maybe 3000 people. Indris was then converted to Eastern Orthodoxy, under the name of Leonty, and his sons as Konstantin and Feodor. Konstantin's grandson Andrei Kharitonovich was nicknamed Tolstoy (fatso) by Vasily II of Moscow after he moved from Chernigov to Moscow.
