help with place names please

[asherman]

Can anyone help me with the attached place names please?  The top image is from a marriage register in Holyhead dated 1858.  The 3rd entry on the last image is from the 1861 census.

Apart from the dot the first one looks like Penrhos y fedw.I wonder if this means an abode of Y Fedw in Penrhos(llygwy)?
The second is Garreg Cefn.Again I wonder if this is an abode e.g. in Llanbadrig,not a million miles from Holyhead,Anglesey.

Looks like Penrhos y Feilw is possible for the first:-

The second may be Carreg Cefn rather than Garreg Cefn.If an abode there was one in Llanbadrig
