I'm trying to find a term (other than 'objects' or 'things') which I can use to describe the commonality of substance which all the things that have been named after Nelson Mandela - which include inanimate objects such as buildings, 3.5-million-year-old species of woodpeckers, a species of spider discovered in 2002, and a nuclear particle - share in common.
Suggestions which touch on their common attribute of being named after Mandela are useful, but not what I'm after.
The word could be used in a context such as 'Many xxxxxs are named after NM' or 'NM had many xxxxxs named after him.'
