Help With Proper Possessive Apostrophe Placement

Hello

I am having a todo with someone about the name of an organisation and where an apostrophe should sit. The organisation is about the Hector's dolphin (http://en.wikipedia.org/wiki/Hector's_dolphin) named after Sir James Hector. Because they are his dolphins, and there was one of him, the apostrophe is good where it is. But, the organisation that looks after them is called Hector's Protectors, now is that still correct? Given that they are protecting all of the Hector's - what is the the plural of a Hector's? And as the organisation *are* the dolphins' protectors, they belong to the dolphins, now it seems like it should be Hector'ss' Protectors

What's right here?

Thank you
