Vincent?

I hadn't seen this picture until recently, but this barefoot youngster is much like I imagine Vincent.  The photograph was taken by London photographer John Thomson sometime in the 1870's.  The lad was known as Little Mic-Mac Gosling and although he was 17 years old, he stood only 3'10".  That sounds shocking, but look at the grown men in the background.  I'd guess their height at 5'6" to 5'8" or so.

There are more of Thomson's pictures at Spitalfields Life, a terrific blog about a fascinating section of London.
