This is probably a bit late now but I have just come across this thread. My maiden name is Pluck and I have typed out a copy of a document I have from the historical research centre outlining the origins of the surname Pluck.
It is on my family tree "Pluck Family Tree."
My branch of the family have lived in New Zealand since 1873
and I have found out a lot about the Plucks' since I have been researching my roots.
