Yes it does say servant and single,though this is a "dittoed" single,perhaps to be treated with caution.I think column 16 says "Glam",presumably for Glamorgan as part of the attempt to qualify the addreses.I'm not sure what,if anything,the servant status implies,attached to the family or just locally employed.
However,the following seems more than a coincidence:-
The Hannah Jones(mother) identified in my previous post(1871 Aberangell) may well be Hannah Morgans married to John Jones 1859(checking reference)
In 1891 she is widowed,living in Towyn,where Hannah Richards(nee Jones) gives birth to two chidren around this time.
Her son John is with her and he is an enameller at this time,the same as William Richard is given in 1901.
Refefences for Hannah(mother) and John
