Both sides of the Fëanor/Fingolfin split seemed to have stayed in contact with Fingon. And the House of Finarfin seems to have liked him a lot as well.

True :)

as long as he was present in a given situation, and apparently had Fingon at his back, he seemed to get along well enough with everyone and be able to keep the blows at bay among the more contentious members of his extended family (even if it meant he had to hold Caranthir in a neck lock).

Also true. He must have had a heck of a personality to harness those brothers (mostly - look what Celegorm and Curufin did when they went their own way.) Also I think they loved him :)

what is a party without this woman?

Haha :)

Lovely, Osuhun.

What fun! :) This kinda reminds of what my friend and co-worker went through when she recently planned who was going to sit next to whom at her wedding. I didn't envy her ;) But certainly, I wouldn't have liked to miss a family reunion at the Finweans'.
