Hello,
It's sometimes not so easy to link 1911 with 1901 in the case of unusual family surnames.
For example, 'Moderic' in 1911 would be 'Madéries' in 1901.
http://automatedgenealogy.com/census11/ ... #highlightYou, first of all, click on a neighbour family already linked in 1911 and probably living in the same subdistrict of interest in 1901. In that same subdistrict in 1901, you then click on the subdistrict reference id. You'll then be enabled to view all the families in that subdistrict where you'll spot the answer.
Good luck.
