Ellen Harvelle
Ellen started out working in the Road
House to make enough money to go to
school.  But that seems like a hundred
years and a different life time ago to her
now.

She fell in love with the boss's son Bill,
and they got married shortly before her
father and mother in law were killed. That
was her introduction to the supernatural,
and to John Winchester who had come
through hunting the same creature.
She was the one that introduced
John and Maggie, even though
she didnt approve of the
relationship, for Maggie's sake.

It was only Ellen's loyalty to that
friendship that kept Maggie from
killing her daughter in retaliation
against Bill.

She met John's boys after his
death, and has done her best to
step in as a surrogate parent of
sorts to them.
