Ralph, I have Sayle ancestors in Andreas, who married (several times!) Radcliffe and Teare - three of the most common names there. They were a real headache trying to trace correctly.
But it is possible, with wills probably being the best source for the really common names in an area.

If you are able to work out your ones past Peel to Andreas, I have gathered a lot of Andreas Sayle records over the years.
