Is there any grammatical error in this sentence?

Question

or any error

or something improper

↓

"she doesn’t know that he is in Canada nor his name."

Answer 1

You have a double negative problem. "Doesn't" modifies the verb "know" and the two clauses are joined with a negative conjunction "nor."

To check it, take out the negatives.

"She knows that he is in Canada or his name."

Corrected Sentence:

"She doesn't know that he is in Canada nor does she know his name."

Actually, this is just a really weird sentence structure and meaning. I'd probably restructure it to the following.

"She doesn't know his name nor that he is in Canada."

Answer 2

She doesn't know that he is in Canada, nor does she know his name.

Note to Yve:  

Should be -- She doesn't know his name OR (not NOR) that he is in Canada.

Answer 3

Honestly, I am good at grammar but can not detect any sort of error. However the sentence doesn't sound right. I would say, "She doesn't know his name, nor that he is in Canada." It just flows better.
