I wonder, if you were to add some sources for Alexander Knox Dysart, including his birth, marriage and children, if you would have a different response from the Profile Manager of the Premier of NB.
If I was the PM for a notable, and someone asked me to add this profile as his father, it would go on my to-do list, and it would wait for the work to be completed to find sources confirming that this is the same Alexander Dysart noted on the Premier's death certificate. Speaking for myself, I generally get a more positive response from a PM when I have taken the time to do the legwork myself. In this case, the Premier's profile is project protected, but potential father is open and could use some sources.
Just a thought, I hope its helpful.
