It would be a good idea to include some dates for them, if you have any. Westbroom might be West Brome, I think. And your Bushey might be Boucher. I can find two Oliver Busheys in the census records - one in Compton and one in Dunham. The one in Compton was born 1840 and the one in Dunham 1829. I might be more interested in the Dunham one, if I were you - that is more in the area of Brome.
