Help with 1891 census please

[slewis]

Hello
  I am looking for David Roberts born abt 1853 Lanwrin, Montgomeryshire.

I have found him with his parents Griffith Robert born abt 1825 Llandwrog,  Margaret born abt 1827 Llanwrin, on the 1861 / 71 and  81 census but had no luck with the 1891census.

 1871 David was working in a quarry like his father, in 1871 they lived at 3 Beyneglwys Llanfihangel y Pennant, and 1881 Collage green.
If you can help I would really appreciat it.
                     Regards Sue
