When I write:
A father_of B
I get an error 'pedigree must have at least 2 founders'
similarly, when I write:
A father_of C
B mother_of C
C mother_of D
I get an error 'Subjects must have both a father and mother, or have neither 1/4'
It would be better to just automatically create the missing person (i.e. a mother for B in the first example and a father for C in the second example)
