Gilbert fitzreinfrid son and Heir...Christina &Ivo

Good Morning,
I have found a reference, but once again it screws the timeline up,
dubious, as everything with this line, but others may know more! That is
Christina de Leterham, sister of Gilbert fitzReinfrid, wife of Walter
(Gauthier) de Castlerock of Strickland.
There's that Gilbert fitzReinfrid again! Now there is some family ties.
Maldred, Lord of Atterdale who mar. Aeldgyth(Edith), dau of Uchtred E. of
Northumbria, had Gospatrick whose daughter marr. Orm Lord of Allerdale,
whose granddaughter Ada de Workington mar. William Boteler L of
warrington. Orm's Brother Gilbert de Lancaster mar. Godith whose great
grandaughter married Gilbert FitzReinfrid.
The reason I bring this up is to go back to the above names that started
part of this whole thing with Gilbert fitzReinfrid.
1. Is Ethelred really son of Ivo Taillebois?
a. At this samae time period and connect to the family AND land is
Ethelred,(grt nephew of Maldred, L. of Allerdale), who is Earl of Fife
whose family marries with the Lindseys who married into the children and
grandchildren of Gilbert fitReinfrid and Hawise de Lancaster with back and
forth marriages between the Peter de Brus and the Lindseys and the
fitzReinfrid's 1 and 2 generations later.This later I will take to the
Boteler's, Lindsey's, Brus' of Skelton that I think is a tad cobbled)and
tied in.
b. Ethelred, Earl of Fife, great grandson is also Orm, of the same time
period.
2. Ivo. a. I have seen Ivo as
the son of Reinfrid and brother Roger fitzReinfrid whose son allegedly was
Gilbert fitzReinfrid, then again a timeline problem and inter-marriage
problem.
b. I have seen Ivo as the son of Count Fulk IV and his brother Count Fulk
V and King of Jerusalem.
c. I have seen Ivo as the son of fitzRichard de Roumare.
d. Hugh de Grentemesnil, High Steward of England under WTC, 5th son was
also Ivo mar. Rhoese dau. of Gilbert de Gant. Ivo exiled 1102.
e. Ranulph III de Meschines mar. as the 3rd husband of Lucia widow of Ivo
Taillebois her 1st, Aelgar Earl of Mercia her 2nd, Ranulph and Lucia had
William L. of Bolingboke, Earl of Lincoln mar. Hawise dau. of Richard de
Reviers, Their daughter Rhoese mar. 1st Gilbert de Gant and 2ndly Roger
fitzReinfrid father of Gilbert FitzReinfrid.
All of these for the same time periods,places, and wonder if the old
records merely transferred known names to known places but should have
been ascribed to another line?
I hope this is a little better understood and do truly apologize Todd for
the way I write, I do write it on paper before I type, I re-read it who
knows how many times before I submit and in my mind I still read the same,
but you are correct, 24 hours later I read it and I know what I mean but
it doesn't read that way. I will try to be more careful somehow.
Best Regards,
Emmett L. Butler
