Hi Colin,
By the 1911 Census, Robert Roberts is deceased as his wife Jane is living with her daughter and son in law Edward and Mary Ann Williams with Mary Ann's son John H Roberts living at Bryn Hyfryd Pwllglas.
Robert and Jane Roberts had 4 children, Margaret, Robert, Jane and Mary Anne. I have bought recently death in 1911 and 1904 both incorrect and have sent for Ruthin district, is this where I'm going wrong?
Kind regards
Nerys
