Ancestors of Flavius Eparchius Philagrius // Comes Orientis abt 382 Bishop of Cyprus; Prefect of Egipt?

I'm Just subscribed on this forum. Hello and Happy New Year to everyone!

Does someone knows something about the ancestors of

Flavius Eparchius Philagrius // Comes Orientis abt 382 Bishop of Cyprus;
Prefect of Egipt?

His attested wife was Egnatia Avita Severa, daughter of Quintus Flavius
Egnatius Placidus Severus // (48260) (abt 330A.D. - ) and Antonia
Marcianilla // (48259) (abt 335A.D. - )
His sons:
1) Eparchius virus nob. of Toul // noble of Toulouse (48262) (abt
370A.D. - )
2) Agricola Consul of /ROMAN EMPIRE/ Prefect of Gaul; Consul 421 (34161)
(abt 370A.D. - aft 421A.D.)
3) Lysticius // (176757) (abt 375A.D. - )

I'm very interested to find the male lineage of this Flavius Eparchius
Philagrius, supposed to be my oldest direct MALE ancestor (45
generations).
I'm not sure about is father, that could be Flavius Philagrius //
Prefect of Egypt between 334 and 340 (176649) (abt 300A.D. - aft
340A.D.), cited on "History Of The Decline And Fall Of The Roman Empire
- Volume II" by Edward Gibbon, on note 111
