General Notes

With his father, he was given partial custody of the castle of Tillieres in
1013/14. He was a haughty and powerful man - the banner brearer of all
Normandy. He founded the abbey of Conches in 1035. While Duke ROBERT
(RIN 1323) was away on pilgrimage, Roger went to Spain and had a
distinguished career fighting the infidel there. While in Spain, he
married [Etienette of Barcelona according to Cokayne's "Complete
Peerage", but later research, as per below, indicates ADELAIDE OF
BARCELONA], but left her behind when, due to the treachary of some of
the natives, he had to leave Spain. When he returned to Normandy, he was
furious to learn that the boy WILLIAM (RIN 798) has succeeded his father
as Duke, declaring that a bastard ought not rule over him and other
Normans. Roger immediately rebelled, ravaging the lands of his
neighbors - particulary those of HUMPHREY DE VIELLES (RIN 1036).
HUMPHREY's son, ROGER DE BEAUMONT (RIN 1033) killed Roger and two of
his sons in battle in 1038/9.

Thus the following points can be made. Stephanie is a red herring. She
was not daughter of Countess Ermesende, nor was she sister of Ramon
Berenguer. Any chronological argument involving her can be rejected.
Second, since Ermesende was grandmother of Ramon Berenguer, the wife
could not have been both daughter of one and sister of the other. Either
the chronicler was in error, confusing Berenguer Ramon with his son
Ramon Berenguer, or there were two marriages involved, the solution
proposed by Evans. The use by the Todeni of Belvoir family of the name
Berenger de Todeni (also known as Berenger Hispina, a nickname I have
seen elsewhere translated, I don't know how accurately, as "of Spain")
suggested to Evans that this line descended from a Barcelona marriage,
and he proposed that Roger de Toni married Adelaide, daughter of Ramon
Borrell and Ermesende, while a kinsman, married her niece (perhaps
named Stephanie) sister of Ramon Berenguer. (I don't have the reference
handy, so I may have this confused in detail.) Note that any attempt to
number the early Counts of Barcelona or Kings of Navarre will end in
frustration. I have seen three different numbering systems for
Barcelona, and I have seen this Garcia Sanchez called anything from
III-V.
