Inspired by this thread–which celebrities have the most intertwined families, biological and adopted.
The award is obviously named after Mia Farrow–three biological sons and three adopted daughters with Andre Previn, a biological son and two adopted children with Woody Allen, and five adopted children on her own. Two of her adopted daughers married brothers, making for grandchilren who are double first cousins.
The David McCallum/Jill Ireland/Charles Bronson clan is pretty convoluted–Jill and David married, had a son, then Jill had a miscarriage. The Jill started an affair with Charles Bronson, who had a son and daughter by his then-wife. Then Jill and David adopted a son and nine months later had a son (who looks like a clone of Daivd). Then David left Jill for model Kathy Carpenter and they had a son and daughter. Then Jill married Charles and had a daughter, and took in the daughter of a friend who died suddently. The whole scorecard is six parents, two adopted children, seven biological.
