In Viking tradition, take this into consideration that a single name is used for a couple to many generations so they made nicknames that may not show in official records. I found a few of these in the Orm/Gamel/Gamal/Gamle line. I highly suspect lineage to the Norse royalty as evidenced by name and sheer wealth (and marrying into the most prominent family in Northumbria)
Literature states one of the Orm's was Gamal's father while historians say no, he's the brother. Because some of this is in archeological record, Orm/Gamal are father, brother, son depending on the generation. I'll update my line later as I get better dates and have more time to sift through the latin.
I believe your Orm is the son of the Orm I have:
Orm/Ormerod/Arm/Orn/Ornus/Ormus of Ormesby b. 965AD-1041AD (Ormerod means snake or dragon-it's a Viking name)
Orm refurbished the oldest Saxon church in England of Kirkdale
Married: Etheldritha (b., daughter of Earl Aldred Lord of Welbure
Son: Gamel
Son: Roger de Burton of Burton in Kendal
Son: Orm de Ashton of Ashton under Lyne
Daughter: Ecgfrida
(I may need to add another Orm after review but I've been spending most my time looking for grandparents of this Orm).
FYI for research (you likely know) Von, Fitz, Del, D', Vel, -rod -sby are all "of (meaning place) or born from (meeaning child of). I also found lots by spelling names according to Dane, Norse and Saxon variations which are all different.
