Ealdred, Earl of Northumbria & Bernicia - Who was the mother of Ealdred, Earl of Northumbria & Bernicia?

Sharon Doubell can we clarify? There’s conflicting evidence.

Your curator note has:

Ealdred, Earl of Bernicia
Parents: Uchtred, Earl of Northumbria & Ecgfrida, daughter of Aldhun, bishop of Durham.

Uchtred "the Bold", Earl of Northumbria & Ecgfrida

However, Anne Bergen’s curator note for his father has:
Uchtred of Northumbria. Son of Waltheof & his wife. Married: 1. Ecgfrida
2. Sigen 3. Ælfgifu, daughter of Æthelred.
Children: w Sigen: 1. Ealdred. 2. Eadwulf 3. Gospatric.
w Ælfgifu: 1. Ealdgyth 2. daughter, marrried Æthelgar

Sigen Styrsdóttir

According to MedLands

• UHTRED, son of WALTHEOF Earl of Northumbria & his wife --- (-murdered 1016).
  • m firstly (repudiated) as her first husband, ECGFRIDA, daughter of ALDUN Bishop of Durham & his wife --- (

    , bur Durham).
  • m secondly SIGEN, daughter of STYR Ulfsson & his wife ---. Simeon of Durham's Account of the Siege of Durham records the marriage of "Cospatric's son…Ucthred" (although from the context "Cospatric" appears to be an error for "Waltheof") and "the daughter of a rich citizen…Styr the son of Ulf…Sigen"[427].
  • m thirdly ([1009/16]) ÆLFGIFU, daughter of ÆTHELRED II King of England & his first wife Ælfgiva ---.

Earl Uhtred & his [second] wife had three children:
1. EALDRED (-murdered Risewood 1039). … m ---. The name of Ealdred's wife is not known. Ealdred & his wife had five children: …
2. EADWULF (-murdered 1041). Simeon of Durham names "Aldred, Eadulf and Cospatric" as the three sons of "Uchtred"[449]. Earl of Northumbria. m as her second husband, SIGRIDA, [widow] of ARKIL (son of Fridegist), daughter of KILVERT & his wife Ecgfrida. Eadwulf & his wife had [two] children: …
3. GOSPATRICK . m ---. The name of Gospatrick's wife is not known. Gospatrick & his wife had one child: …

The tree looks correct, it’s just the curator note?

Also, the name of Ealdred’s daughter, Etheldritha who married Orm fitz Gamel is also seen as Aetheldryth and as Aethelflaed. I’m pretty sure they’re all the same person but a double check wouldn’t hurt.
