In my research for a friend I've come across a man who married his step-daughter (in the 1860's) which I am assuming wasn't allowed under law. Am I correct? He had children by his first wife, and then by his step daughter - so their children were also his step grandchildren. He died and his widow remarried. Her daughter then married her new husband's son (by a previous marriage) - so they were step siblings. And I thought my family was complicated! Lin A true friend walks in when the world walks out
