Ella, your Pascoes are a difficult bunch!!
All I can find is the following in Llangonoyd, Glamorgan at Maesteg;
Thos John age 61 occ lab born in county
Ann John age 60 ditto
Ann Lewis age 35 ditto
Paulinus Lewis age 10 ditto
Catherine Pascoe age 25 ditto
Henry Pascoe age 6 ditto
Ann Pascoe age 3months ditto.
Looks like she's visiting parents? and they've told fibs as to where children are born. Cant find any sign of William, but the son of Ann Lewis having the name of Paulinus makes me think they are the ones you're after.
