Is Snape Riddle's Nephew?

Before you call me an idiot, think , not about Snape and Tom 
Riddle .... but about their mothers.

Merope Gaunt had a "heavy face" and, although she wasn't good with 
the wand, was gifted with potion making. She brewed the love potion 
without going to classes and maybe without reading. When she gave 
birth to Tom and gave his name, there were very few living witnesses 
who could say all that happened.

Eileen Prince had "heavy brows". She was very gifted with Potion 
making, as proved by the book that was passed onto Severus. Even 
though Hermione deeply researched the name "Prince", the only one 
she could find was Severus's mother ... no family line was evident 
of Eileen's parents.

If That potion book was about 50 years old when Lupin saw it, that 
would put Eileen in Hogwarts at the same time as Tom Riddle. It 
could be they were in the same year and so the same age. That got me 
thinking ...

What if Merope had TWINS !!! Tom and Eileen.

Eileen may have been adopted out as a baby, and no word of her was 
given to Tom since he was hard enough to handle in the orphanage 
already. The woman who talked to Dumbledore was distraught while 
talking anything about Tom Riddle, so Dumbledore could have easily 
missed signals that there was a twin sister.

She displayed magical abilities just as other Muggle borns did, and 
would have been invited to Hogwarts at the same time as Tom. Then, 
several years after leaving school, she married Tobas Snape ... a 
muggle, just like Merope did.

Not saying it is true ... just What if it is true? How would that 
change the way Voldemort seemed to forgive and trust Snape? How 
would that connect their abilities of mind reading?

I hope I haven't become the one you love to argue against now.

discussion is going)
