With all due respect, that reason shouldn't factor in at all. Why? If you look at the chain of generations up or down by more than about three generations it will be made up of people who have or who will never meet you and to whom you will be but an abstraction. Also, your degree of genetic relatedness to your descendants will be halved with each passing generation. Ten generations down the line your direct descendants might as well be perfect strangers.
