To do a parent search on Family Search, go to the International Genealogica Index (IGI) screen. Simply put in full father and mother's names on the r/h side and then British Isles/ Scotland. Sometimes when you do this type of search you may see results for more than one couple with the same names, you can then add time filters and/or counties (although be aware that people moved around more and you may miss some births if not in the counties you are expecting).
