Friends I can offer Murdock Greyback - he needs some buds, and they are about the same age. Possibly either knew each other from school - or via the ministry or both.

Thaddeus might be more casually friendly, but i doubt they are close pals

Isis Silverthorne could be a professional contact, in that she brings in cargo, could be used for animal transfers, she regularly goes to foreign arts and parts.

I have hurls by way of Christabel Daphnel as a widow, who might be more of a fail hurl, since she's so intense - or Madeleine Backus - she's younger, but could be good options for a 'you've got mail' style hurl plot
