A handsome fellow from Norwich

Another delve into the Victorian album from Mum's bookshelf, and this time I wonder who this handsome chap could be.

He was surely a relative of mine since the picture was taken in Norwich but which of the great greats he might be is anyone's guess.

No date and no clue as to the sitter, but it was probably taken around about 1892, or maybe a little earlier as the Norfolk CC website suggests 1888, since the purple stamp on the beautifully presented cabinet photo indicates that the photo was taken in Gavin and Banger's St Giles' Studio (they had three studios in Norwich , according to earlyphotographers.org).

The old White Lion Street can be seen, as my great great might have seen it as he walked around the centre of Norwich, on this picture from the Norfolk CC website

Any further information about sitter or photographer gratefully received.

A Victorian photo album: Who are the musicians in this photo?

As well as books collected from around the family, Mum also loved photos and had shelves full of photo albums. The oldest of the albums is this one full of Victorian cabinet photos.

I have no idea if the people in the pictures are members of my family although many of the pictures were taken in Suffolk studios, where both my paternal and maternal relatives are from. It's an intriguing set of photos.

I wonder, for example, who these people are and why they are clutching mandolins, surrounded by cowbells. There's no clues on the back of the photo, not even in which studio it was taken.
Were they a popular musical group who sold pictures of themselves? A musical off-shoot of my family?

I'd love to know.
