What is the effect of having no knowledge of the relationship between her lover and her husband when she became pregnant?

Given the facts as we know them, the mother could have had no knowledge as to whether her lover or her husband was the father of the child. This rather obvious fact was stated most eloquently in Pike v. The People, 34 111. App. 112 (1889), where the following was stated (at p. 113): That it is only by inference that the mother can afterwards fix the paternity of her offspring when she submits herself to the embrace of several at or about the same time she became pregnant, and in so doing she places it out of her power to draw any safe conclusion upon that subject.
