    From statement I: E is the brother of F, who has only one son. H is the mother of G. E has parents. K is the grandson of I. D is married. G has only one daughter. I is the father-in-law of F. D is either mother or father of E, also, we have no information given about J, so, statement alone is not sufficient to answer. From statement II: F is the wife of G. H is the mother-in-law of G and married to I. E is not married to D. J is not married. G has only one daughter. I is the father-in-law of F. So, statement II alone is also not sufficient to answer the question.   From statements I and II: So, J is the granddaughter of D.
