Help dating this Snook portrait please

[paulanthony262003]

This portrait of my ancestor hangs at my grandmother's house. 
It was left to her, by her father, my great-grandfather, who lived 1893-1959.

I think it might be one of three ancestors:
my 2xgreat-grandfather, 1865-1934,
my 3xgreat-grandfather, 1832-1904,
my 4xgreat-grandfather, 1800-1841.

Although it could conceivably be my 5xgreat-grandfather who lived 1760-1836.

Unfortunately, it is not signed or dated on the front, and I am not allowed to remove it from the wall to see the back for labels or other clues of who painted, when or where.

I'd appreciate some thoughts and opinions on this please.

Im no expert, but its looks 1700's etc. Ask granny nicely, to let you see the back!

Possibly 4th or 5th great grandfather.

It may not have been contemporay though - my initial mpression is that it was painted more recently than during either of those men's lifetimes.

Hi Paul...how big is the framed picture? I'm thinking 3 x Great Grandfather.

Hi Carol, thank you,
It is roughly similar to A3 size, maybe slightly smaller but certainly not larger than that.

A variety of opinions so far on this topic, any expert opinions please?

[Regorian]

I'm not an expert, but 4X 1800 to 1841 is best fit. Towards the end of his life I'm afraid.

[Ruskie]

The sitter appears to be in his 20s ... I am guessing.

I would think there is no harm in taking it off the wall and looking for clues at the back of the framed painting.  (if you, do please take some photos which may help ID it). Without seeing it in the flesh it is difficult to judge the age of the painting, but looking at the back might at least give clues as to when it was (last) framed.

I don't think it is a professionally painted portrait - possibly executed by a competent amateur. It may even have been painted by a family member.

I'm not convinced that this is a painting...I would stick my neck out and say this is a hand tinted 1860s enlargement. There doesn't appear to be any texture to it and the facial proportions appear more photographic.
Just my opinion.

It is difficult to see from the photo, but it does appear to be quite 'flat', and I was going to ask about the texture and if the paint was cracked at all. What struck me was the use of overly heavy black (?) to highlight the features of the face. Not a style you would see in the 17/1800s I don't think.
