I just saw your query even though its an old one. The West family have been in Anglont Co Kerry for a long time. A John, Joseph and a William all appear in Griffiths Valuations in 1851 as having land in Anglont. Anglont is a townland near Killorglin and Milltown Co Kerry.
In the 1901 census there is a William West there. I know this because my greatgrandfather Walter Eagar was living on his land.
There are still Wests living there today.
On the 11th Dec 1850 a William West married a Jane Neill which is probably the one appearing in Griffiths.
