Cleon Broadmoor was her house and yearmate. He's close friends with Don Juan and sometimes spends a few nights at the Dempsey estate so she would know him decently well, I imagine.

For potential hurls, I have Desiderius Morgan, Richard Gladstone , Alexander Echelon.

Potential friends could be Loretta Browne and Victoria Fudge who were each a couple of years below her but in the same house.
