The sources for Halfdan are the "Skaldaskaparmål", "Ættartalur" and "Hversum Noregr Byggdist".
He is not to be confused with Halfdan Gamle, son of Sveidi, from the Orkney saga.
King Halfdan Hringsson "the Old" In Ringerik - was born about 0450 in Ringerike, Buskerud, Norway. He is the son of Hring Raumsson.
King Halfdan married Almveigu Eymundsdatter about 0479 in Ringerike, Buskerud, Norway. Almveigu was born about 0455, lived in Holmgarth, Novgorod, Russia. She is the daughter of King Eymund In Holmgard.
According to the sagas, Halfdan had 18 sons, nine of them born at a single birth. Quoth Wikipedia:
the first, Thengil [Thengill], who was called Thengil of Men;
the second, Ræsir;
the third, Gram [Gramr];
the fourth, Gylfi;
the fifth, Hilmir;
the sixth, Jöfur [J%C7%ABfurr];
the seventh, Tyggi;
the eighth, Skyli or Skúli;
the ninth, Harri or Herra.
These nine brothers became so famous in foraying that, in all records since, their names are used as titles of rank, even as the name of King or that of Jarl. They had no children, and all fell in battle.
Halfdan and his wife had nine other sons also; these were:
Halfdan the Old (Old Norse Hálfdanr gamli and Hálfdanr inn gamli) was an ancient, legendary king from whom descended many of the most notable lineages of legend. A second Halfdan the Old is the purported great-grandfather of Ragnvald Eysteinsson.
Hyndluljód
The eddic poem Hyndluljód states in verses 14–16:
"Of old the noblest of all was Áli,
Before him Halfdan, foremost of Skjöldungs [Skj%C7%ABldungar];
Famed were the battles the hero fought,
To the corners of heaven his deeds were carried.
"Strengthened by Eymund [Eymundr], the strongest of men,
Sigtrygg [Sigtryggr] he slew with the ice-cold sword;
His bride was Álmveig [%C3%81lmveigr], the best of women,
And eighteen boys did Álmveig bear him.
"Hence come the Skjöldungs, hence the Skilfings,
Hence the Ödlings [%C7%AA%C3%B0lingar], hence the Ynglings,
Hence come the free-born, hence the high-born,
The noblest of men that in Midgard dwell:
And all are thy kinsmen, Óttar, thou fool!"
Though Halfdan is himself called a Skjöldung in verse 14, in verse 16 the Skjöldungs are named instead as one of the families that sprang from Halfdan's marriage with Álmveig.
Ættartolur
Halfdan and his sons
The Ættartolur, the genealogies appended to the Hversu Noregr byggdist in the Flatey Book introduce Halfdan the Old as the ruler of Ringiríki (a territory including modern Ringerike and Valdres in Oppland). Halfdan is here the son of King Hring (eponym of Ringeríki) by the daughter of a sea-king named Vífil (Vífill). Hring was son of Raum the Old (eponym of Raumaríki) by Hild (Hildr) the daughter Gudröd the Old (Guðrǫðr inn gamli). Raum the Old was son of Nór (Nórr) (the eponym of Norway). See Nór for further details about Nór and his ancestry and descendants.
In his sacrifice Halfdan requested a lifetime of 300 years like that of his ancestor Snær. The form Tiggi appears instead of Tyggi in the list of the first nine sons. The list of the second nine sons has Skelfir instead of Yngvi and the form Næfil (Næfill) instead of Nefir. The order of the names is the same and it is explained that Hildir, Sigar, and Lofdi were war-kings; Audi, Budli, and Næfil were sea-kings, while Dag, Skelfir, and Bragi remained on their lands.
Halvdan Ringson, konge på Ringerike og Valdres
Han var sønn l kong Raum, Hans kone hette Almveig, datteren til Vifill sjøkonge
De hadde 18 sønner 9 av dem hadde ikke etterkommere, De andre 9 er det fortalt om her i Hvorledes Norge ble bosatt
Sønnen deres var Halfdan den gamle Da han tok kongedømmet gjorde han et stort blot midt på vinteren og blotet fordi han skulle kunne leve tre hundre vintre i kongedømmet sitt, slik det ble sagt at Snær den gamle hadde. Men gudene fortalte ham at han ikke skulle leve lenger enn en mannsalder, men den kunne være tre hundre vintre og at det ikke fikk være noen uadelig mann i hans ætt og ingen kvinne. Han var en stor hærmann og herjet vidt og bredt i Austerveg. Der drepte han i tvekamp den kongen som het Sigtrygg.
Han giftet seg med Ålfnya, datter til kong Eymund i Holmgard
De hadde ni sønner. En het Thengil, men ble kalt Mannathengil. Ræsir, Gram, Gylfi, Hilmir, Jøfur, Tiggi, Skyli og Harri; om disse ni ble det sagt at de alle ble jevngamle og de ble så navngjetne at deres navn var mer kjent enn navnene til både rangspersoner og kongelige. Det fortelles at ingen av dem hadde barn, og at alle siden falt i kamp.
Likevel hadde de ni andre sønner. De het: Hildir, Næfil, Audi, Skelfir, Dag, Bragi, Budli, Lofdi, Sigar. Hildir, Sigar og Lofdi var alle hærkonger; Audi, Budli og Næfil var sjøkonger, mens Dag, Skelfir og Bragi styrte over land.
