Here's the list I found. I haven't checked or edited anything so there may be mistakes:
On the beard-colour thing. I know quite a few men with brown hair and red (or redder) beards. There seems to be something that makes the redness show through more in the beards. Never met a man with a golden beard and different coloured hair, though.

Uncle Andrew: Grey, MN Ch. 1

Dr. Cornelius Silvery beard, balding in pic PC Ch. 4

Roonwit: Golden beard, chestnut flanks, TLB Ch. 2
Edmund: In HHB he is described as the “leader of the fair-haired men”, HHB Ch. 4
