Unknown Antique Painting - Russian???

Not much what I can say about the painting... my dad found in an old woman's home after she died. It appears to be an oil painting, 19th century perhaps. The person in the painting has factions pertaining to be Russian but all of this is uncertain as I am no expert. The frame appears to be old as well. The signature located on the bottom left is very faint. It appears to spell out "Laeffle". The frame is old and appears to have a signature in a different handwritting "Kedpo".... I would appreciate any piece of information that can be provided, possible origin, who is the person in the painting, possible value... Thanks, Chris
