Welsh hand writing street or house name

[PamSquam]

Hi, I am hoping someone can tell me what the street or house name is for the first record here for Charles Bliss.  It is not repeated on the page before nor on this page.

It's in a village called Machen near Caerphilly wales. Although a lot of the other property names I have come across in this area have been English words so the welsh might be a red herring.  I just can't get this one sorry.

Many thanks in advance for anyone that can help.

The nearest that I can find on a map is Nant y ceisiad

Added - sorry I forgot to say that it looks like Nant y cesha - so nearest was this

I should think that Gadget has got it right; the entry is very much like what a non-Welsh-speaker would have made of the map name.

The mystery word is familiar to me as some of my Vaughan family lived there in 1830s and later.
To quote from my [unpublished!] family history: "The locality of Nant-y-ceisiad ST 202 891 lies above the present east-west road, A468; it takes its name from the brook (Nant) that ran down to the Rhymney River".
 ST 202 891 is the Ordnance Survey map reference.
I don't think the enumerator would have been a non-Welshspeaker - just that the name had/has a few variations possible in Monmouthshire Welsh dialect.
