Looking for Margaret Adams Affleck Parents

Margaret Adams AFFLECK was born abt 1855 in Biggar, Larnarkshire, Scotland. She married William BEVERLAND (or possibly BAVERLAND) in 1872 in Wishaw, Cambusnethan, Larnarkshire, Scotland. Margaret is my great-grandmother. Margaret and William emigrated to New Zealand.
Margaret's parents were Thomas AFFLECK and Elizabeth ADAMS, who are my great-great-grandparents. I am looking for information about them.
Any information would be gratefully received. Thanks
