Here are a few references as to your post in "Fellow Curators - Help please or explain!"
It would seem Unknown Profile & Hawise de Redvers are the same but whether she was the wife to both Robert FitzRobert, Castellan of Gloucester & JORDAN De CAMBERNON, I cannot say as these references only list Robert.
The sister Attavis (Avis) de Redvers is connected as wife to Gilbert de Soligny but there is no mention of her on the references, but on http://en.wikipedia.org/wiki/Umberleigh "Gilbert/Phillip de Soleigny married Avis (or Hawis) de Redvers, daughter of "Baldwin de Redvers, Earl of Devon",[6] and according to Risdon the sister of "Richard Rivers, Earl of Devon", probably Richard de Redvers, 4th Earl of Devon (d.1193). For her dowry Hawis was given by her father the manor of Stoke Rivers, which thus passed to her husband.[7] Gilbert/Phillip de Soligny left a daughter Mabill de Soligny as sole heiress, who married Jordan de Champernon, into whose family Umberleigh passed."

Hawis' daughter Mabel married Jordan de Champernoun, seigneur de Cambernon.
Mabel Champernon (Soligny)
It appears the profile for Hawise de Vernon (de Reviers) is incorrect with the marriage to JORDAN De CAMBERNON as she only had one marriage to FitzRobert.
The below profies are a mess.
JORDAN De CAMBERNON Unknown Profile
and
Jordan de CHAMPERNON Jordan Seigneur de Maisoncelles de Champernon
http://archiver.rootsweb.ancestry.com/th/read/GEN-MEDIEVAL/1999-02/...
1. JORDAN de CHAMBERNUN. Seigneur de Cambernon and Maisoncelles in
Normandy, France. In 1146 Jordan de Campo Ernulfi was first witness of a
confirming charter of Henry de Tracy, then Baron of Barnstaple to the Priory of
St. Mary Magdalene, Barnstaple, Devonshire. He appears to have died by 1166,
when his sons Jordan and Henry were in possession of his lands.
He married, as her first husband, Mabel, daughter of Robert, son of
Robert, Earl of Gloucester, and Hawise, daughter of Baldwin de Redvers, 1st
Earl of Devon. Mabel married 2ndly, William de Soliers. As Mabel de Soliers,
she confirmed in c1193-1204 a gift charter of the manors of Fleet and Ibberton,
Dorsetshire from her mother, Hawise, to her son, Richard de Chambernun.
(Charters of the Redvers Family, 11, 146; DCNQ, 18: 3-7, 81-84, 108-112,
319-320)
Children:
2. Jordan de Chambernun, m. Emma de Soligny.
3. Richard de Chambernun.
4. Henry de Chambernun, m. Rose de Tracy.
So writing down what you both said above in the form of a tree we still have conflict:
It seems to me that Mabel/Mabil married Jordan Champernon and that she was the daughter of Hawis/Hawise/Avis but was her father Robert fitzRobert Castellan of Glos. (s/o Robert Earl of Glos) or was her father Gilbert/Philip Soligny?
Could 'William de Soliers' be the same as Gilbert/Philip de Soligny?
It seems that Emma de Soligny and Mabil de Soligny are one and the same person and it seems unlikely that if Hawise/Avis was one person that she married Gilbert/Philip Soligny as this would mean brother and sister marrying which leads then to the question of who Gilbert/Philip Soligny did marry i.e. who were Emma's parents..... Oh dear! Mabel and Emma cannot possibly be the same person.... there I go getting in knots again!
I'm just the amateur here, so maybe I should set back & let you solve this one, but I'm really getting confused. I had Mabel FitzRoberts m. Jordan Champernon. Mabel as the daughter of Robert "the Kings Son" deCaen, 1st Earl of Gloucester, Earl of Meullent & Maud (Mabel) FitzHammon de Meullent, dau. of Robert FitzHammon Lord of Glamorgan & Creully & Sibyl de Montgomery.
Robert was the son of Henri I & Concubine 1.
Does any of this make sense with what you're saying? And is Jordan de Champernon the same person as Jordan de Cambernon?
Jordan de Champernon is my 25th & 28th ggf...which makes it even more confusing keeping 2 lines straight. Does this make sense?
Hawise de Redvers m. Phillip de Soligny
dau. Mabel (Emma?) de Soligny m. Jordan1 (b.1096) de Champernon*

Mabel FitzRobert dau. of Robert "the King's Son" de Caen, Earl of Gloucester, Earl of Meullent m. Maud (Mabel) FitzHammon de Meullent (dau. of Robert FitzHammon Lord of Glamorgan & Creully & Sibyl de Montgomery). Robert is the ill. son of Henri I & Concubine #1.
