Check out what Erin did for the Nova Scotia Premiers (e.g. Henry Hicks ... link attached). In the Succession box she has a 'Space' category so, when you click on the 'Premier of Nova Scotia' link you get this nice list of all of 'em ... well done, Erin!
So, the real question is, do we want to do something similar for all of our lists? Prime Ministers, Fathers of Confederation (I know, there's no succession there!), Province/Colony Premiers, more to come ... I'd say 'YES' unless there's some snag I'm not aware of ... whatcha all think?
Other projects with Succession may want to consider this too.
