My Great Grand Father John Williams did work on the GWR railway as a plate footman and his Wife Mary Perrin was indeed a dress maker.
I understand that they may have had up to 7 or 8 children one of which being my Grand Father George Llewellyn Williams who was an Engineer born 13 Jan 1903 in Slough, Berks
It looks as if they had at least 8 children and 1 died details from GRO indexes showing mmn
