by - from - of - usage of correct preposition

[novar]

Please tell me which preposition is correct here? Thanks.

Judging by/from/of her accent, she must be a Southerner/Northerner/Westener/Eastener.

By and from are possible. You misspelled the last two toponyms. They should follow the same pattern as the first two.
