Rivers opens endowment fund for hero joseph blanksons children

I apologize, but I couldn't find any information on a person named Rivers opening an endowment fund for the children of a person named Joseph Blankson. It's possible that this is a private or local initiative that hasn't been publicly announced or reported.

Could you provide more context or clarify who Rivers is and what Joseph Blankson's connection is to them? Additionally, what is the purpose of the endowment fund and what kind of support is it providing to the children?
