A collective noun refers to the collection of things taken as a whole.
A family is the perfect example of individuals coming together and our three children all have their middles names in common:
Hunter Finch, Harper Heron and Banjo Hawk.
We've taken the collective to include their middle names in these three meads.
A Charm of Finches is Blackberry Charm, A Seige of Herons is Saison Siege and a Cast of Hawks is Cast Net. They're all different, surprisingly delightful, curious and definitely one of a kinds.
