Interesting, but didn't the Duras assist the Romulans? I wouldn't trust the House of Duras any further than I could throw a Pakled.
Well Ja'rod's children would only have been very young at the time, and so not having any part in their father's dealings. But knowing the characters of the Duras siblings, would any of them have chosen to join Starfleet, as Worf did? Would they even have remained in the Federation?
