The island was closed on 23 March.
On its Facebook page, an update was posted saying Herm islanders, who refer to themselves as Hermites, were all eternally grateful to everyone who works hard to get supplies across and distributes them to the 65 residents at their houses.
A Herm Island spokesman reserved special praise for three young people, Will Knight, Emily Stamp and Morgan Jones.
‘Unfortunately, some suppliers have struggled to fulfil everyone’s grocery orders in Herm as they simply don’t have the time or manpower to source and pack the orders – and we completely understand and thank them for the efforts they do make on our behalf.
‘Many Herm households didn’t receive their groceries last week so Will, Emily and Morgan, who live in Guernsey but have family in Herm, decided to help ease the pressure off the Guernsey suppliers and do all the dry goods shopping for islanders.’
After several hours of queuing and shopping, they took everything home to bag, box and label and deliver to go with the rest of the deliveries for the Herm cargo boat on Wednesday.
Will grew up in Herm and now works for Herm & Guernsey Oysters. His parents and two brothers are currently in isolation in Herm.
Will’s partner, Emily, is an essential worker in Guernsey and Morgan is the daughter of Tom and Rachel from the Mermaid Tavern and is currently working from home for her Guernsey employer.
All three share a flat so are isolating together.
Morgan said: ‘We were all more than happy to help, we know how it feels to be stuck in Herm and we want to help our families and other residents.’
The Herm Island spokesman thanked them for their help in keeping the Hermites fed.
They also thanked Justin De Carteret, from Herm & Guernsey Oysters, who has been their man on the ground in Guernsey providing a vital additional lifeline for collection and delivery of anything from food and household goods to prescriptions and even a puppy needing a vaccination.
