McBrides states Waltheof's father as Sigurd, Earl of Northumbria married to Aelflaed, daughter of Aldred of Bernicia.
dchull royal geneaolgy has no father listed for Waltheof.
LDS records state Waltheof's father is Siward Bjornsson married to Aelflaed, daughter of Aldred of Bernicia.
Siward was a Danish follower of Canute and was rewarded with the title of Earl of Northumbria. In 1032 he also became Earl of Deira in 1032. In 1054 Siward led a successful invasion of Scotland and after defeating Macbeth he replaced him as King of Scots with Malcolm Canmore. Siward died in 1055 and was replaced by Tostig as Earl of Northumbria. http://www.spartacus.schoolnet.co.uk/NORsiward.htm
Sigurd the Dane, also known as Siward (d. 1055), was an English nobleman in the eleventh century, and the earl of Northumbria.
Siward was a descendant of the Danish royal family, whose ancestors may have arrived in England a few generations earlier as part of the Norse colonisation of Britain. Some historians suggest that Siward arrived in England with King Canute and that Canute invested the title and position of Earl of York onto him in 1031. At the time Canute was replacing all the old Anglo-Saxon nobility with his own trusted men.

Who is who differs tremendously here. Someone's father is elsewhere that person's son.
He was the third surviving son out of four of Clotaire I and Ingund. His reign found him mostly occupied with a successful civil war against his half brother, Chilperic.
When Clotaire I died in 561, his kingdom was divided, in accordance with Frankish custom, among his four sons: Sigebert became king of the northeastern portion, known as Austrasia, with its capital at Rheims, to which he added further territory on the death of his brother, Charibert, in 567 or 568; Charbiert himself had received the kingdom centred on Paris; Guntram received the Kingdom of Burgundy with its capital at Orléans; and the youngest son, the aforementiond Chilperic, received Soissons, which became Neustria when he received his share of Charibert's kingdom. Incursions by the Avars, a fierce nomadic tribe related to the Huns, caused Sigebert to move his capital from Rheims to Metz. He repelled their attacks twice, in 562 and c.568. About 567, he married Brunhilda, daughter of the Visigothic king Athanagild. This marriage, if we take the chief chronicler of the age, Gregory of Tours, at his word, reveals something about Sigebert's superior character in that violent and lascivious age. Now when king Sigebert saw that his brothers were taking wives unworthy of them, and to their disgrace were actually marrying slave women, he sent an embassy into Spain and with many gifts asked for Brunhilda, daughter of king Athanagild. She was a maiden beautiful in her person, lovely to look at, virtuous and wellbehaved, with good sense and a pleasant address. Her father did not refuse, but sent her to the king I have named with great treasures. And the king collected his chief men, made ready a feast, and took her as his wife amid great joy and mirth. And though she was a follower of the Arian law she was converted by the preaching of the bishops and the admonition of the king him self, and she confessed the blessed Trinity in unity, and believed and was baptized. And she still remains catholic in Christ's name. [1]
Upon seeing this, Chilperic, the most base of Sigebert's brothers, sent to Athanagild for his other daughter's hand. This daughter, Galswintha, was given him and he abandoned his other wives. However, he soon tired of her and had her murdered in order to marry Fredegund, Sigebert sought revenge. The two brothers had already been at war, but their hostility now elevated into a long and bitter war that was continued by the descendants of both.
In 573, Sigebert took possession of Poitiers and Touraine, and conquered most of his kingdom. Chilperic then hid in Tournai. But at Sigebert's moment of triumph, when he had just been declared king by Chilperic's subjects at Vitry, he was struck down by two assassins working for Fredegund.
He was succeeded by his son Childebert under the regency of Brunhilda. Brunhilda and Childebert quickly put themselves under the protection of Guntram, who eventually adopted Childebert as his own son and heir.

Sigebert III (c.630-656/660) was the king of Austrasia from 634 to his death on probably 1 February in 656, or maybe as late as 660. He was the eldest son of Dagobert I.
To satisfy the Austrasian aristocracy, who exercised a certain autonomy, Sigebert's father gave him the kingdom of Austrasia although it remained part of the larger Frankish realm. On the death of Dagobert, Sigebert ruled Austrasia independently, and free from any subjection to Neustria.
He tried in vain to add Thuringia to his kingdom, but was defeated by Duke Radulph in 640. Though only ten years of age, he was the leader of his army. The Chronicle of Fredegar records that the route left him weeping in his saddle. From this, we can surmise that, at least in part, the downfall of the Merovingian dynasty was a result of child rule, for both Sigebert and his younger brother Clovis II, who ruled in Neustria, were prepubescent children who could not fight on the field and whose regents had their own interests at heart.
It was under his reign that the mayor of the palace began to play the most important role in the political life of Austrasia. That mayor, Grimoald, the son of Pepin I, managed to convince the king to adopt his son Childebert. When Sigebert finally had a son of his own, the future Dagobert II, the mayor of the palace felt threatened, and on the death of Sigebert he exiled the young Dagobert to Ireland. Sigebert's remains, defiled during the French Revolution, are preserved in the cathedral at Nancy.
It is notable that he is often described as the first roi fainéant—do-nothing king—of the Merovingian dynasty.

Olof of Sweden or Olof Skötkonung/Skottkonung was the son of Eric the Victorious and Sigrid the Haughty. He was probably born in the latter part of the 960s and he succeeded his father ca 994. Our knowledge of Olof is mostly based on Snorri Sturluson's accounts, which have been subject to criticism from source-critical scholars.
The meaning of the cognomen Skötkonung is disputed. One theory holds that "Sk" /?/ is an ancient version or distortion of "G" /j/, and that thus, "Skötkonung" /?ø?tko?n???/ would really be "Götkonung" /jø?tko?n???/, meaning "King of the Geatas".
According to the Sagas, his father Eric the Victorious ruled together with Eric's brother Olof Björnsson. When Olof Björnsson died, Olof was proclaimed co-ruler instead of his cousin Styrbjörn Starke. This happened before he was even born. At his father's death, he inherited the throne of Sweden and became its sole ruler.
In a Viking expedition to Wendland, he had captured Edla, the daughter of a Wendish chieftain, and she gave him the son Emund (who was to become king of Sweden), and the daughter Astrid. He later married Estrid, a Christian girl and she bore him the son Anund Jacob and the daughter Ingegerd Olofsdotter.
Olof is said to have preferred royal sports to war and therefore, Sweyn Forkbeard retook Denmark, which Olof's father Eric had conquered. Olof also lost the right to tribute which his predecessors long had preserved in the Baltic States.
In 1000, he allied with Sweyn Forkbeard, who was married to Olof's mother, and with the Norwegian Jarls Eric and Sven, against the Norwegian King Olaf Tryggvason. Olaf Tryggvason died in the Battle of Svolder and Olof gained a part of Trøndelag as well as modern Bohuslän.
When the Norwegian kingdom was reestablished by Olaf II of Norway, a new war erupted between Norway and Sweden. Many men in both Sweden and Norway tried to reconcile the kings. In 1018, Olof's cousin, the earl of Westrogothia, Ragnvald Ulfsson and the Norwegian king's emissaries Björn Stallare and Halte Skeggesson had arrived at the thing of Uppsala in an attempt to sway the Swedish king to accept peace and as a warrant marry his daughter Ingegerd Olofsdotter to the king of Norway. The Swedish king was greatly angered and threatened to banish Ragnvald from his kingdom, but Ragnvald was supported by his foster-father Thorgny Lawspeaker, who was the wisest and most respected man in Sweden.
Thorgny rose and delivered a powerful speech in which he reminded the king of the great Viking expeditions in the East that predecessors such as Erik Eymundsson and Björn had undertaken, without having the hubris not to listen to his men's advice. Torgny, himself, had taken part in many successful pillaging expeditions with Olof's father Eric the Victorious and even Eric had listened to his men. The present king wanted nothing but Norway, which no Swedish king before him had desired. This displeased the Swedish people, who were eager to follow the king on new ventures in the East to win back the kingdoms that paid tribute to his ancestors, but it was the wish of the people that the king make peace with the king of Norway and give him his daughter Ingegerd as queen.
Thorgny finished his speech by saying: if you do not desire to do so, we shall assault you and kill you and not brook anymore of your warmongering and obstinacy. Our ancestors have done so, who at Mula thing threw five kings in a well, kings who were too arrogant as you are against us.
These arguments convinced Olof to follow his people's advice. However, Olof showed no signs of wanting to keep his promise, but married his daughter to Yaroslav I the Wise instead, and then the Swedes became restless. However, the impending rebellion was settled when Olof agreed to share his power with his son Anund Jacob. Olof was also forced to accept a settlement with Olaf II of Norway at Kungahälla, who already had been married (unbeknownst to Olof) with Olof's daughter, Astrid, through the Geatish jarl Ragnvald Ulfsson.
Olof was baptised, probably by the missionary Sigfrid, c.1008, and he was the first Swedish king to remain Christian until his death. However, according to Adam of Bremen, the fact that the vast majority of the Swedes were still pagan forced him to limit Christian activities to the already Christian border province of Westrogothia.
His death is said to have taken place in the winter of 1020-1021.
Since the 1740s, it has been claimed that he was buried in Husaby in the Christian part of his kingdom, but it should be noted that such identifications are speculation, and by no means uncontroversial.
