There is an error in the comparison between the maps and the census enumerator's records. 'Fach' lies west of Brithdir - further along the valley. This property is actually FAWR and is likely to have been the property shown in 1871 - see separate entry
Note: Inhabited by a labourer and not, apparently, a farm
Note: apparently not a farm. Now occupied by a miner
Note: Shown as inhabited by a colliery labourer, and no longer appears to be a farm
