General Notes

The following information, which indicates that there is not much solid evidence on Baldric, is contained in a post-em by Curt Hoffeman, curt_hofemann@@yahoo.com.  Based on it, I added Aimee de Brionne as a wife.  However I kept Muriel as mother of Baldric's 1st two children.  However unlikely, this leaves Baldric marrying 1st the illegitimate daughter of Richard I of Normandy, and 2nd his great granddaughter.

FWIW (caveat emptor):

But the names "GILBERT" and "GEOFFREY" as the early ancestors of the DE NEVILLES on your list might indicate some likelihood that Baudric's wife was indeed a niece of Gilbert de Brionne, as written by Orderic.  Orderic not only stated the fact about the niece of GILBERT marrying "BALDRIC,"  but named their six sons, including Nicholas DE BASKERVILLE and Richard DE NEVILLE, according to P. H. Baskervill...

In my letter to GEN-MEDIEVAL, I also said that BAUDRY/BAUDRIC le TEUTON and his brother WIGER came to Normandy and put themselves at the service of WILLIAM I, but it was not WILLIAM I, but WILLIAM's grandfather, Richard II of Normandy (996-1026) they served under, according to Orderic. 

Abbe' Daoust states that BAUDRY married AUBREE, niece of Gilbert DE BRIONNE. This is the first place I have seen the name of the niece. [Ref: Kay Roemer <roemer222@@aol.com> 9 Jan 2001 message to Gen-Medieval]

I have read that Gilbert's (de Brionne) niece Aubree married Baudric le Teuton and named a son Fulk, who later became Fulk d'Aunou. [Ref: Kay Roemir roemer222@@aol.com 24 Jan 2001 message to Gen-Medieval]

Research note: Baldricus Teutonicus De Bacqueville, Lord Bacqueville & Caux... (married) Denefacta De Brienne (dau of Robert De Brienne, Count of Eu & Beatrice De Falaise [Ref: (unsourced) http://users.legacyfamilytree.com/NorthernEurope/f223.htm]

In reality, the dearth of records about him suggests any ancestry is speculatve  (at best) not supported by reliable records (those that do are only guesses - my  opinion only)... Curt
