I would consider the first one (coming of age) as an Evolution story for sure – becoming a father/becoming an adult is absolutely there. If you wanted to deal with the pressures of living up to parenthood or being a parent, that would be in Expectation (living up to the expected ideals of parenthood).
The second would depend on the context of the story. I tried my best to stay away from creating subgenres that were specifically positive or negative, since it forces writers into a certain area of storytelling. I could see either of those being Becoming or Being, depending on how the story was written.
The Past and Obtaining? In the same storyform?
That is definitely possible, but I can’t add it to the list without Dramatica-approved examples! The Mind Domain was quite a challenge in that way.
