Young siblings Duncan and Lily Nelless, who live in Longhorsley, have recently handed over £1,000 to HospiceCare North Northumberland.
The money was collected during a table-top sale at their grandparents’ bed and breakfast.
It is the third donation they have made to the charity in the last 24 months, bringing the total to well over £2,000.
The pair wanted to ‘give something back’ to HospiceCare, which supported a close member of their family.
Julie Frost, from the charity, said: “Duncan and Lily are complete superstars and are our youngest fund-raising ambassadors.
“Their commitment to raise funds for us is simply astonishing and they are already planning another table-top sale.”
