Prayers are being held for Declan Donnelly's brother, Father Dermott Donnelly, who is said to be "extremely unwell" in hospital.
The Catholic community has been sending well wishes to Fr. Dermott after it was announced that he has been admitted to hospital and is believed to be seriously ill.
Pontop Partnership, which is a partnership of ten Catholic parishes in the Diocese of Hexham and Newcastle, announced the news on Facebook.
