For the benefit of those that find Othere of Haolgalander in various books, Tom Magness has contributed the following discussion:

Here's what Round had to say about Other . . .

"In The Earls of Kildare we read that 'In 1078 Walter fitz Otho is mentioned in Domesday Book as being in possession of his father's estates.' To this statement, which is obstinately repeated in the pages of Burke's Peerage, I reply, as in Peerage Studies (p. 69), that the date of Domesday Book was 1086, not 1078; that Walter was the son of Other, not Otho; and, that Domesday does not state that his lands had been held by his father, but, on the contrary, proves them to have belonged to forfeited Englishmen." (Round, FitzGeralds, ii., p.121-22) "Thus, the 'Otho' story is shown to be absolute fiction." (Round, Peerage Studies, p. 69)

And, here's what Collins had to say about Other . . .

"Othoere is mentioned, in the appendix (vide p. 205) to The Life of King Alfred, to be living in his reign, a rich and powerful Lord, and to derive his descent from ancestors in the kingdom of Norway. It also appears, that Other, as wrote in the Doomsday Book (Ex lib. vocat. Doomsday), was living in England in the reign of King Edward the Confessor; and in the pedigrees is made to be the son of Othoere." (Collins, Peerage, vol. 4, Windsor, Earl of Plymouth, pp. 37-38.)

Add to Collins this piece of information, from Fisher's Anglo-Saxon Age . . .

Othoere of Haolgalander, frequent guest of Alfred, King of Wessex (871-99), who was "among the foremost men in his land; even so he had not more than twenty head of cattle and twenty sheep and twenty pigs, and the little that he ploughed he ploughed with horses. His principal wealth was derived partly from fishing for walrus and whale but was chiefly derived from tribute in skins and furs levied from the Lapps who lived further north, and it was in order to dispose of these goods that he traveled to England."

There is mention on page 19 of the Brut Y Tywysogion: Chronicle of the Princes (edited by Rev. John Williams ab Ithel) for the year 910 . . .

Nine hundred and ten was the year of Christ, when Other came to the island of Britain.

A thorough reading of the Doomsday Book reveals the only mention of Other is as father of Walter the tenant-in-chief of lands in Berks, Bucks, Hants, Middlesex and Surrey. Collins assumes that Other was a contemporary of Edward the Confessor because he found a pedigree that made Other the son of Othoere. What pedigree that is Collins fails to note.

To my way of thinking the threads that tie Other to Othoere are just too weak to be accepted.

Then there is Round. No doubt Round was aware of the Collins article (1812) but did not give it any credence in his work on the origins of Carew (1903) which is the best reason not to include it in the data base.

. . . and, perhaps our ancestors concocted the 'Geraldini' relationship because they were embarrassed about being descended from one of the "foremost farmers of the Anglo-Saxon era.”

Wikipedia http://en.wikipedia.org/wiki/Account_of_the_Viking_Othere (Feb 25, 2006) has this to say:

Ottar from Hålogaland
From Wikipedia, the free encyclopedia
(Redirected from Account of the Viking Othere)

Ottar from Hålogaland was a Viking adventurer from Hålogaland. Around 890 he traveled to England, and Alfred the Great had his tales written down.

Ottar told that he lived farthest to the north of all the Norwegians. He told about his travels to the Bjarmaland (White Sea), and south to England, accurately describing the entire Norwegian coast. He told about the Sami people, Swedes and Cwens.

Ottar's tales are the earliest known written source using the term Norwegians.

Ottar lived in Troms, probably somewhere just north of Harstad, maybe on Senja (todays Lenvik is seen as most probable) or slightly furter north (Kvaløya or Karlsøy).
