Confirmed facts:

1 - Viserys I is the grandson of Jaehaerys I.

​2 - Rhaenys is the daughter of "Aemon Targaryen" and Jocelyn Baratheon.

3 - Rhaenys is the mother of Viserys I.

Viserys I is Jaehaerys I's *grandson*, so we cannot simply insert another intervening generation. It is "Jaehaerys I-->???-->Viserys I"

If it was "Jaehaerys I-->Aemon-->Rhaenys-->Viserys I" that would make Viserys I his *GREAT*-grandson....which is impossible, given that the books have stated he was his "grandson" not "great-grandson".

This leads me to suspect that Aemon may have been a younger brother of Jaehaerys and Alysanne.

Baelon was apparently Jaehaerys I's son, though I cannot confirm this.

Other confirmed facts:

4 - Jaehaerys chose Baelon over Rhaenys in 92 AL. Apparently this wasn't considered a "Great Council".

5 - The later "Great Council of 101 AL", apparently made after the sudden death of Baelon, once again skipped over Rhaenys.

Given that the RESULT of the 101 council was that Viserys I would succeed....Rhaenys's own SON, I suspect that the 101 council was unfairly confirming that a woman shouldn't rule, by skipping to her own son. Then again, maybe it wasn't Rhaenys, but Viserys I's father who was important.
