Blair's daughter Margaret was married to Malcolm Landgraab III. His aspiration is Knowledge and his zodiac sign is Gemini. As far as personality he is quite outgoing and very active. But he is quite serious, rather grouchy, and a little bit on the sloppy side.
Like most deceased Sims, Blair has no skill points, and what skills he may have had in life are unknown. According to his SimDNA in SimPE, his hair was blond before it turned grey. According to Blair's age data, he had 14 days left in the elderlife stage when he died.
Blair's face is identical to a pre-made face from Create a Sim. The face is in the bin for elder males with light skin (skin tone 1), and has short messy hair and glasses. This CAS face, if used on toddlers or children, has a shrunken chin and plump face. Chester Gieke, Jason Greenman, Gabe O'Mackey, and Trent Traveller use slightly modified versions of this face.
