The story was widely publicised in the British press, although its truthfulness was called into question. According to the charity Adults Affected by Adoption, there had been other cases of this sort that had involved siblings. One supposed case of incest between twins, in which twins who were adopted by separate families as infants later married without knowing they were brother and sister, was mentioned in a House of Lords debate on the Human Fertility and Embryology Bill in January 2008. Incest between twins or ' twincest' is a subclass of sibling incest and includes both heterosexual and homosexual relationships.
