Going back to the Anwyl Roberts`s ,
I did a search on the 19th century newspapers site, just for Anwyl Roberts, and there are many `hits`.
I don`t which are linked, but these are a few I found.

HARVEST THANKSGIVING SERVICES
North Wales Chronicle (Bangor, Wales), Saturday, October 25, 1873
Llanfairmathafarneithaf Anglesey.
Rev Anwyl Roberts MA rector of the parish read the prayers.
There are many more reports regarding Rev Anwyl Roberts, the above vicar of Anglesey from 1874 to 1875 regarding his drunkeness

and misconduct.
It seems that frequently there was no one at services apart from the vicar and his clerk.
The principal landowner in the parish , Mrs Lewis died and according to custom her funeral service was expected to held the following Sunday. A very large congregation assembled, but - no vicar !!!.
Charges were brought against him and reports were made in national papers headed the Anglesey Clerical Scandal.
To be fair there here was another clergyman charged at the same time with falsly registering the death of his daughters illegitimate child.
Nothing at all to do with our subject, but just a bit of scandal
