I'm stuck on finding the last dynasty member (currently have 6) and I need the final one for the final trophy to get the Platinum trophy.
I've found some forum posts mentioning that you can get a dynasty member in the start of the Colonial era and the Modern era (in Sandbox mode), after sending a dynasty member to Harvard university that gives you an option to take on a heir after a 'reckless night' done by the dynasty member. I got one from the Colonial era, but did not get one from the Modern era.
I got a total of 6 in the campaign, but one was killed when I sent it off to negotiate with the rebels, so I was left with 5 when I finished the campaign. Maybe this is why I'm stuck with 6?
I've also tried starting a new campaign with my dynasty members, but did not get the option to take on a heir after sending one of my dynasty members to Harvard.
Is there anything I can do?
