Ladoga, Indiana Ladoga, Indiana Ladoga is a town in Clark Township, Montgomery County, in the U.S. state of Indiana. The population was 985 at the 2010 census. Ladoga was platted in 1836 by John Myers. Myers invited his friends to help him find a name. He required that the name not end in -burg or -ville and that it would not be named after another town. He chose Ladoga after finding Lake Ladoga on a map of Russia. In 1837, the town's post office was established, which still operates today. In 1840 there were fifteen buildings in Ladoga, including two large stores
Lake Ladoga "neva" "bog, quagmire". Ancient Norse sagas and Hanseatic treaties both mention a city made of lakes named Old Norse Aldeigja or Aldoga. Since the beginning of the 14th century this hydronym was commonly known as "Ladoga". According to T. N. Jackson, it can be taken "almost for granted, that the name of Ladoga first referred to the river, then the city, and only then the lake." Therefore, he considers the primary hydronym Ladoga to originate in the eponymous inflow to the lower reaches of the Volkhov River whose Finnic name was Alodejoki (corresponding to modern ) "river of the lowlands".
