How hard can it be?

Last month I could search away on ancestry, but now
I type in a christian name, surname, birth year give or take 2 and presto ............................ only results from the English census not the Welsh. So I go to the Wales 1881 census punch in the details, John Williams, 1839, wales, glamorgan, merthyr tydfil, male, and presto up come the reults with 1 or 2 stars first, the first names begining with A.
What am I doing wrong,?
A very frusted Drewllyd!
