Hello Hugo,
The properties nearby in the 1851 census are as follows:
Preceding Maes on the census, Pen y Bont and Ffordd. The occupants were the household of Robert Williams in Pen y Bont and of Hugh Williams in Ffordd.
The next household after Moses Jones in Maes, is shown as living in Maes again, this time it is John Owens and family. The properties after that are Waen Fynydd, occupant Elinor Roberts and household, then Bwlch Glas, occupied by John Evans and family.
In the 1841 census, Moses Jones is living in Maes but the surrounding houses are different. These are:
preceding Maes, Garth, occupied by Robert Williams, Farmer, then Twullyog (not sure of spelling) occupied by Elias Roberts and family.
After Maes, Ty Gefn, occupied by Robert Roberts and family, Fron, occupied by Hugh Williams, Farmer, then Ffordd, occupied by Evan Williams, Farmer.
I take it that both Moses Jones and family and John Owens and family lived in Maes but they are shown as two separate households.
Helig.
