I can’t find any information about Lexsy, but it was a small crossroads settlement at one time, with at least one general store. It had a post office from 1899-1967. This house was likely the largest in the area.
The plank walls are in relatively good shape; mantles have been removed from the fireplaces.
A shingle roof, likely added in the last 30 years to replace the tin or shake original, is probably the only reason the house is still standing.
