who was 2nd 3rd and 4th oldest Hammonds?

We know John Anderson was the oldest, the patriarch. And we know Jimmy was the baby of the bunch. So who was 2nd, 3rd, and 4th oldest. As 2nd son of my family, I always root for the 2nd son.

I think since Drury and Sylvus roomed together, they were consecutive-no proof, just a probability. Sylvus did the cooking, and seemed to be one of the younger ones to me. Plus Oates had a lot of authority. I think Oates was the secon oldest of the Hammond, Drury the 3rd, and Sylvus the 4th. Does anyone know for sure? Anyone got any ideas?

Plus Oates had that mean Simeon streak, who was the second son of Jacob. Maybe Peckinpah meant for a correlation there.

Now go away or I shall taunt you a second time
