Incorrect Harry Potter Game?

so, with who and why did it end, if it did?)

Severus Snape (or, if you will, Perseus Evans, the black-sheep half-
brother of Lily and Petunia) had an extended liaison with a Hogsmeade 
lady of easy virtue a little over ten years ago, who later married a 
muggle who did not officially adopt her child.

Since this question was in the realm of out-of-canon speculation, so 
is the next one:
Does Snape know about the child he fathered? And, if so, what will be 
his reaction to the child's imminent matriculation at Hogwarts?
