I didn't find out for years, but I fathered a child with a woman in my neighborhood who was, and still is, married to another man. The girl does not know about any of this. Neither does the husband. At the mother's request, I have had nothing to do with the girl, though I offered to tutor her. Does she have a right to know her true parentage upon reaching adulthood? Sooner? Over the objection of her mother? Only when her current husband dies? Who can make these decisions and when?
