It looks to me like most of the houses have names - in part of the 1841 census addresses are just "werm" -so maybe the address was 8 Werm??
there was an independant chapel built 1770 named Capel Als (Alice) on Marble Hall Rd/Werm Rd which in 1851 had at least 1000 worshipping there
The description of the enumerator's walk in 1841 is "all that part of the Borough Hamlet lying to the right of the road through the Wern from its junction with Westfal? to ?wppellal?? & from there to Marble Hall

"The Wern" refers to a rough area of Llanelli which includes the modern day Wern Road and Ann Street and a lot of the area at the base of Bigyn Hill. Capel Als is still there at the very north of Wern Road and at the bottom of Marble Hall Road, opposite the pub "The Half Moon". This area was my paper round when I was a young girl in the 1970s
This area is not in the modern Glyn electoral ward, which, as stated earlier is much further north and includes Ponthenri and Sylen etc, but whether it was in the Glyn area in the 1840s I couldn't tell you.
"Westfal?" I'm not sure about, although it could be Westfa which is one of the old divisions of Llanelli, although I would associate this with the Felinfoel area, but again it might have bordered the Wern area in those days, I couldn't be sure.
"?wppellal??" Mistranslation of Capel Als maybe? sounds phonetically similar
I found this information which might be of interest to you
"Before the advent of the Workhouse in Llanelli, the poor and destitute were given sanctuary and refuge in alms houses. These were situated at The 'Wern', a district of Llanelli that lies below the slopes of Bigyn Hill. Life in these cottages was described in the closing years of the Victorian era, as being 'infinitely more humane than that of the Union Workhouse by which they were succeeded'. The present day 'Cwrt Elusendy', off Wern Road stands in their place." link below
