Hi and welcome to Rootschat
I found this entry in 1891 Wales census for Armor E Lloyd, I'm sure it's Trevor on original.
RG12/4567 F40 P 10
Bank House, Builth
Sarah Lloyd 42, widow, b Brecon
Harry S 9, b Cwbran, Mon
Armor E 8, b Cwbran Mon
Gilbert T 7 b Cwbran
Perhaps someone else could take a look and see.
