It does look like Oulet Hall on the parish register, but on the 1841 census it definitely says Owlet Hall, and there are six households living there.
It isn't Nether Hall, John, as that is in District 8 of Kirkheaton in 1841, whereas Owlet Hall is in District 9, in between Cold Royd and Mill Lane. From the 1854 map Mill Lane looks to be at the end of Crossley Lane so Owlet Hall must have been along there somewhere.
