Help with the definition of authorship
 

Hello dear forum users!

Please help identify the possible author of this picture.
The picture is painted in oil on canvas, about 1800 ...
year.
Thank you.

Even judging by their clothes, some 1800 can not be.
Definitely the second half, towards the end, the 19 th century.
Amateur artist when the work on signed, the author did not identify.

All signs copies of an amateur ...

Thanks for the help, as I understood, this work is not of interest.
