I realise that the Webb attribution has been blown, but to follow up on the Fereday name. Jason Ellis does not mention a George at all in his book "Glassmakers of Stourbridge and Dudley 1612-2002". the only two Feredays are mentioned on page 474, note 53:
"John Thomas Fereday, son of Joseph Fereday, who ran a grocery shop in Church Street, Kingswinford and his wife Sarah; b 18th Mar 1854, Kingswinford; PRO 1881 cencus of Kingswinford RG11/2893/6; d. 28th Feb 1942 at Llandudno."
I am therefore guessing (from this well researched source) that there was no George L Fereday and that it arose from one original misconception being copied by others.
