I've just come across the following book which has only the Currey surname
indexed (no lines which a Curry married into) and will do lookups if this
surname is of interest to you.
The Currey Family in the Hudson Highlands: Descendants of Richard Currey of
Peekskill Hollow, New York by Philip Field Horne. 
And before someone asks, no, Philip Horne is no relation to me.
