dear krish, dont want to pry, but if you dont mind..were these the only two children? or were there others?
i think given acceptance, there is a good chance, that our traditions will be respected and followed, if our youngster has feelings for our values. in many cases, they dont care or are against it,which is why, they convert. very few cases of compulsion, and that mostly due to circumstances. this is my opinion.
for those settled in the west, there is no issues of relatives. and most of their children marry away from the community, for many reasons, one of the main ones being, that the parents dont object. and the concept of love enters into the equation
