Ancestry of Gaius Calpurnius Piso problems

[Divus Iulius]

Gaius Calpurnius Piso was the lead conspirator to the Pisonian Conspiracy, and trying to construct his family tree.

 

The pages on Wikipedia of these people, i tend to find contradictions or errors...

 

The Brother of "Gaius C. Piso" was "Lucius Calpurnius Piso Frugi Licianus". this guy, became Emperor for 5 days.

 

Then the father of Gaius C. Piso", would then be "Marcus Licianus Crassus Frugi", and mother

being "Scribonia Magna".

 

Pompey The Great (Married) Mucia Tertia

|

Pompeia Magna = Lucius Cornelius Cinna

|

Cornelia Pompeia = Lucius Scribonius Libo (Consul 16)

|

Scribonia Magna = Marcus Licianus Crassus Frugi

|

Gaius C. Piso and Lucius C.Piso

 

 

This is were things do not make sense, "Lucius Scribonius Libo", was the grandson of another "Lucius Scribonius Libo", whom married "Cornelia Sulla", the daughter of Pompeia Magna

 

http://en.wikipedia.org/wiki/Lucius_Scribonius_Libo

 

L. Scribonius Libo (praetor 80 BC)

Whom had married Cornelia Sulla, the daughter of Pompeia Magna (daughter of triumvir Pompey from his third marriage to Mucia Tertia)

 

L. Scribonius Libo (consul 16 AD) (Grandson of Above)

Whom married Cornelia Pompeia Magna, who was the daughter of Pompeia Magna (daughter of triumvir Pompey from his third marriage to Mucia Tertia)

 

This family tree is not possible ?

[Pompieus]

Gaius Calpurnius Piso, the central figure in the conspiracy against Nero in 65, was the guy who was relieved of his wife (Livilla Orestilla) by Caligula and exiled in 37-38 AD, then recalled by Claudius and made consul suffectus in 41. Who his father was is not clear. It may have been L Calpurnius Piso (cos 27) in which case his grandfather would have been Gnaeus Calpurnius Piso (cos 7) who was accused of murdering Germanicus. There are other possibilities, the consul of 27 evidently had a brother named Marcus and a L Calpurnius Piso was consul in 57.

 

Lucius Calpurnius Piso Frugi Licinianus was apparently a son of M Licinius Crassus Frugi (cos 27) who was adopted by a Calpurnius Piso, but which one is unknown. Lucius was later adopted by Galba and executed in 69 by Otho. There is a "stemma" of the family of M Licinius Crassus Frugi in Vol X of the 2nd edition of the Cambridge Ancient History pg 992 that shows Licinianus relationship with the Scribonii and Pompeii.

 

Not much help I'm afraid. It is concievable that Crassus let his colleague in the consulship of 27 (L Calpurnius Piso) adopt one of his sons (Licinianus); but that would make it unlikely that Gaius (the conspirator of 65) was the son of that same Calpurnius Piso.
