There might be four (or more).  There might have been a surrogate
mother, and there is some evidence that genetic development is
controlled in the womb in part by the maternal hormonal environment.
The genes we are born with are not exactly the same as the ones in the
fertilized egg, so that a surrogate mother is arguably part of one's
genetic ancestry.
