Things I'm pretty sure I remember correctly:
I've read it in 1992-1993, in a mass market paperback edition. I don't remember anything from the cover.
It was the first of a series.
Synopsis of what I remember from the story.
The hero is an orphan, raised by a wizard. The book opens when the wizard's house is under attack by one of his old enemy whose goal is to get hold of the boy. The attack could have been made possible by the boy or the wizard's negligence. The attack is mostly magical in nature, but the enemy manifest itself as a storm or a strong wind. There is some kind of conversation between the enemy and the wizard. The wizard succeed in saving the boy, but the house is destroyed and the wizard dies after disclosing to the boy his ancestry.
The boy leaves the place were they lived (which was isolated on a road not in much use) and goes to a castle. He gets tentatively accepted there.
The boy goes on a mission with a group of soldiers. They are camping in the ruins of a small old castle when they get attacked. The boy save them -- more because of who he is than what he does. One or two (ghost?) women and ghosts of soldiers having died when defending the castle play a role, IIRC, the women as friend, the ghost soldiers as foes. (ISTR a personal relationship between the boy and the ghost, but fear the influence of the LOTR I read about the same time.) That episode increased the confidence they had he was what he claimed, but he was still not fully accepted.
Things I may get wrong but associate with the book:
the word "chronicle" (I've spend an inordinate amount of time using this to search in various places without finding anything, its probably not part of the title)
the author was English
the author simulated various accent by playing on spelling
