Notes: See stemma for Iulius Caesar for OCTAVANIUS's descendents.
As Munzer noted in RE RE13 can hardly be the grandfather of RE15 as Suetonius states, a generation is missing. Alternative is that RE13 is the younger brother of
RE16 (as proposed by Russel Geer: Suetonis Augustus I, 2 (in The American Journal of Philology Vol.55, 1934 p. 337-339) 
RE79 is called Caius by Suetonius (Aug. 2), but the cos 165 is a Cn.f.Cn.n. Thus either RE79 was a Cn. And Suetonius is in error or if a C. then there must be an
intervening generation and C.Rufus is pushed back to a quaestership c.255.
Articles: Settipani: Continuite p.269-273 discusses Octavius Laenas. He proposes cos 33 married Rubellia, and that cos 131 is his great great grandson,
which is 4 generations in 98 years, one too many in my opinion.
