I can't find a source that names this boy differently than Anthony Chadney, so I'm swimming against the current here, but it can't be him.
Everyone is now in agreement for all the other boys' names, so BOY B can only be either Anthony Chadney or Matthew Horsewood.
So to recap, this is the BOY B we need to identify :
EDIT: We now know that the original list was speculation, so some of the information below has now been found to be incorrect.

In a post above I showed a picture of one possibility, Anthony, a screenshot from a 2001 video, the same year our BOY B picture was taken. Here it is again :

I can see there's a resemblance in haircuts, but look at the nostrils. Every photo I have of Anthony from 1998-2006 shows he has slightly elongated nostrils.

Our BOY B has round nostrils, smaller ears, and although his fringe is similar, Anthony has a cowlick (see photo above).
So I have to conclude it must be Matthew Horsewood, and Anthony wasn't at the photoshoot.
Furthermore, I've also found another clue to bolster the proof against it being Anthony.
This first image is a screenshot from a Libera video in 1999 (2 years before) of an UNKNOWN boy that looks very similar to BOY B. Our BOY B (2001) is alongside for comparison.


The round nostrils and nose shape are the same, haircuts are identical, eyebrows are pale and the same shape, and his own right eye is uncannily the same shape. I think this is the same boy but 2 years apart.
I'd be interested to hear the opinions from bamboo, Liberation, Amie_Hill and The Furby and anyone else that may want to disprove my theory!
