Deadman, could you do a build of Klaus Schneider and Maggie Sr.?
Klaus is known as the "Toymaker", because he's known for his toy based foci and enchanted items (per WoJ, he once took down an SS summonsed demon via magical windup duck). To become this famous, he's probably had to make a lot of toy magic items, which hints at crafting specializations for Thaumaturgy. He's also probably Senior Council level. As for Evocation specialties, we haven't seen a Senior Council level wizard fond of Killing It With Fire, so maybe he's the one?
As for Maggie Sr.: Worldwalking is her Thaumaturgy. This should probably be followed by Transformation and Disruption, based on her NASTY death curse (I think cutting a Whampire off from his Hunger counts as "disruption"), which I'd follow with Summoning. She almost certainly has Worldwalker, and, based on Eb in Blood Rites, probably has Lawbreaker 1st. Based on the way she redeemed herself, I'd only give her the [-1] version, though. Her Intimidation should be pretty high and she probably shares Harry's EPIC WISEASS aspect, based on the conversation Harry has with Luccio in Turn Coat. Based on the way everyone and their brother knows her, her Contacfs are probably up there. Based on how she's known as willful, but not super controlled, I'd make her Conviction higher than her Discipline, like her father and younger son. If elemental specialization is hereditary, then, based on Eb's and Harry's specializations, she probably specializes in Spirit in Evocation. I'd be willing to wager that she'd be able to give Morgan a run for his money in a fight. Just based on intuition.
