Came with William the Conqueror.
No source that I have gives parents for Ives/Ivo.
----------------------------------------------
The following concerns Ives origins in Normandy, prior to the conquest:
Taillebois.
Cristot: Calvados, arr. Caen, cant. Tily-sur-Seulles.
A note in the cartulary of La Trinite de Vendome mentions a copy of the grant of the church and patronage of Cristot by Ives Taillebois to the abbey. An account of Cristot is given in Beziers, "Diocese de Bayeux, vol ii, p. 192. [Origins of Some Anglo-Norman Families]

The following information on Ivo was supplied in a post-em by Curt Hofemann, curt_hofemann@@yahoo.com:
Not much to hang your hat on, but...
Ivo de Talboys. Also called 'cut-bush'. Married Lucy. In charge of siege of Hereward the Wake at Ely, 1069. Steward to William II. Holdings in Lincs. and Norfolk.
[Ref: Domesday Online: http://www.domesdaybook.co.uk/index.html]
The Lancasters are said to be descendants of Ivo de Taillebois and as William was governor of Lancaster Castle assumed the name accordingly. [Stemma Ivonis de Tayleboyse (ex registro S. Mar Ebor New Monast iii 553) Ivo is stated to have had issue Elthred, the father of Ketel, the father of Gilbert, father of Wm of Lancaster who married Gundreda Countess of Warwick. Ketellus filius Elredi was donor of various property to the Abbey of St Mary, York. [Ref: Rosie Bevan 21 Oct 2001 citing The Topographer and Genealogist 1846 p15] note: "is stated" is usually a subtle reference to a difference of opinion amongst scholars... Curt
Research note: "I can't imagine a circumstance under which a Norman named Ivo would have a son named Ealdred. In fact, I can't think of an early Norman that gave an English name to a son. Ivo de Taillebois seems a favorite hook on whom to hang various people of obscure origin". [Ref: TAF 21 Oct 2001] note: though I very much respect his opinion "I can't imagine" & "I can't think of" reveals a prejudice unworthy of TAF. There are medieval parents who gave their children given names that did not exist in their own ancestry & in this instance how better to "fit in" with your conquered subjects than to give your child (who will inherit) a name that his subjects can historically relate to - prosopography has its limits - my humble opinion only...
