As far as my character's families go - 

Nørrevinter - Very well known, hold the pyromancy seat on the council of eight as a hereditary position, and have done so for centuries, so are somewhat akin to akin to magical royalty. This doesn't necessarily mean they're universally liked by other bloodlines, as they're pretty fighty, rather arrogant, and believe themselves to be chosen by the norse gods. This tends to rub a lot of people the wrong way.

The whole Sterling dispute is in some way testimony to that, though has fault on both sides. 

Kingsley - Rune-casters generally, english in origin, once the runic representation on the council of eight, now willingly stepped down from that position The former family head, Arthur Kingsley, refused to offer any aid to the forces against the cult during the war, leading to rumours about their tacit support of the doomsday cult. The rumours are that Aeryn Kingsley ran away to join up, and had a child shortly after her return... a child with a defensive primary, when her fiancee at the time was another rune caster. 
These two things has made them both mistrusted and a laughing stock in equal measure. 


Fox - The Fox family were a pretty famed terramancy family one of the founding council seats. Morgana Fox, Dinah's mother, was a fairly prominent political leader, to the point that her father Matthew, a prominent terramancer of Algonquin descent, took on the name upon marriage. unfortunately the unity between them wasn't all down to primary or personality. It was also that they were both prominent in the doomsday cult, and became pretty key figures in the war.  Their actions after the war made the family a disgrace. Their coat of arms has been removed from all official records and most of the extended family now live wholly outside of the magical community.
