I was curious to see how Geni would handle this. My parents (uncle/aunt) back in the 40's decided it would be cute to throw genealogists a bone, as it were. My uncle began dating my father's sister about the time WWII was getting hot. Well papa met uncle's little sister and guess what? Zygote! Dad's sister is married to Mom's brother. The result? Double cousins! Geni is dumbfounded! If I stuck to the "normal" rules, everything is kosher. Once I defied that rule grandma comes up twice, once as grandma, again as uncle's mother. Himmel! What to do?
