As you say that the KAPPEN families in India are Catholics it is most likely that they arrived in India during the 16th and 17th centuries as during that period in Holland (The Netherlands) Protestant Reformation was taking place (especially in Northern & Western areas of the Country). Of course there were still Catholics in Holland after then (as there is today), but many did leave for other places whilst others decided to convert to Protestants.

The BDM records are reasonable good for this period of time in Holland but you would need to follow your line back in time in India before you could start researching in Holland.

Good luck with it.
