"Customary" doesn't matter much; the maker of a trust can say what he or she wants to say in terms of who takes. The question is a little confusing, but I'm gathering that one child of the trust-maker has passed away, and the trust calls for distribution to the deceased child's children, rather than to the deceased child's spouse. In my experience, yes, that is the more common distribution, keeping the wealth in the lineal family descent. Marriage is a little too dicey these days for many people.
