My main character is a young student at Harvard in 1683. He has been at Harvard for about seven years, getting his A.B. (like a B.A.) in 1680 and now he has gotten his A.D. (Master's degree) in 1683. He loves the place; he will return and teach as a tutor for twelve years, and eventually become the President of the place. But for now, he has graduated and has to leave.

They have trouble getting presidents at Harvard. That's because they need a minister, and they need him to live on-site, and no minister can get their congregation to relieve them, because being minister is like a lifetime commitment. You don't just walk away from a congregation like that. So when Harvard needs a president, they have a hard time finding one.

THey have managed to talk one man into it, though, and he's due to come down with his family of five children, and move to Cambridge from Ipswich where he has been helping another man with a congregation. He's a qualified minister but not a full fledged one and that's why it will work. It takes a while, but finally he arrives and is inaugurated as president, right as our main character is leaving.

This is probably when our main character meets the new president's daughter, whom he will marry in twelve years.

In the year the main character is gone, the new President gets established, but then dies in the middle of a solar eclipse. This is 1684, so there's no telling what people thought of that solar eclipse.

When he comes back, he's a tutor. He's in a better position. He's set to live there for twelve years and ultimately to take over the place. But the daughter is now gone; she's married and had four children, losing two of them. When she comes back, he'll marry her anyway. She's the one for him.
