Okay, Beth here with #8 - Nicodemus Meadowes (and no, I don't have an addiction. I can quit whenever I want to!) younger brother of Dorcas and Astronomy professor/geek extraordinaire. Anyways, about him:
+The youngest child of the Meadowes family and best of friends with Cas
+Has an obvious hostility for
most Blacks given his past and family history (but he's far more accepting of those whom are disowned)
+Was sorted into Ravenclaw and graduated in 1980 (meaning he knows Barty and Rabastan; Regulus was a year before him and same house...so they could've been friends, IDK)
+Took the astronomy position immediately after his schooling
+In 1985, he met his future wife - Lyra Bagnold, an aspiring Magizoologist who was working in Hogsmeade
+Jan 8, 1987, the two of them got married (yes there is a reason why I'm listing these dates)
+Sep 28, 1989, the couple's first and only son (named Alphard goes by the sobriquet of Alfie) was born
+Christmas hols same year, the Blacks staged an attack on Alphard and whilst unsuccessful, they killed Lyra instead, thusly making Nicodemus a widower
+He has never fully gotten over his wife's death and is more than willing to seek revenge when the Blacks mess up
+Usually goes by Nic, Nicodemus, or Professor Meadowes (yes, I know there are two now) only Cas can call him Nici though
+Is a major introvert following Lyra's death
+Also an astronomy buff and knows the stories behind all the constellations (which makes it ironic that Cygnus is next to the constellation Lyra)
And that is it...friends, family, enemies, whatever, the floor is open for discussion/plot
