are the lives of parents worth more

are the lives of parents/carers worth more than childless folks? this popped into my head the other day. is it more moral to let a parent and a childless person die, if you had to choose one?
or, if you were stranded on a desert island with a bunch of other people, and there was one pie that survived as food, should a person with children get the pie?

The asumtion is that you'd be in some disaster and only have time to save one, and know that you only have time for one, knowing that one was a parent and one wasn't, and that you'd be able to weigh the consequences of each in the milli-second before it is too late to act to save either.
Also asuming that you wouldn't simply be running for your own life from whatever.
