Be a post whore!

seven brothers and sisters, most of whom were found to be a match, but they all declined to donate

I wonder why they would be tested for a match, unless they were at least entertaining the possibility of donating. Maybe hoping they wouldn't match and be relieved of the burden of refusing. Or afraid they might look bad to the rest of the family, until one said no and the rest knew they wouldn't be the only one. I supposed if he was an asshole, they all might have been considering it and he said/did something that pissed everyone off.

Not much choice in relatives they're kind of assigned. But your friends you get to choose and there's no obligation to choose any of your relatives.

I understand where the family loyalty, blood is thicker than water, and all those proverbs/slogans came from. How up until a hundred years ago your family was your security, your future, your life. Whether you feel that's for better or worse, that's no longer true.
Some may have split with the family over marriage, religion, sexual orientation, or a million other reasons, and wish they hadn't. But I know for sure there's a few Cellarites who pretty much broke with their families and are better off for it.
