Writing on his Facebook page, he said: "Please can I ask for prayers for my nephew Frankie who is very ill.
"He is my brother John’s eldest son. Many of you will remember Frankie from when we owned the Viking House Hotel. He worked in the bar.
"Please pray for him and his wife and children and John, Bridget and Joey. Prayer is powerful and only God knows the future."
He finished: "Thank you."
The comments were flooded with people sending best wishes to Frankie, with one follower writing: "Sending love and immense prayers of healing, for your nephew Daniel. Love and prayers from Galway."
"Healing prayers for Frankie. And prayers for strength and faith for all his loving family," another wrote.
A third said: "So sad praying for your nephew and hope for a recovery and back home with his family God bless you and his family now and always."
"God bless your nephew frankie and all his family hope he gets better soon Our prayers are with all your family," another said.
It comes as last month Daniel and his wife Majella revealed that they would be welcoming a fourth grandchild. The happy news comes after Majella's son Michael tied the knot to his longtime love Sarah in Italy.
The family enjoyed the destination wedding over the summer, which was also attended by Daniel and Majella's three grandchildren Olivia, Archie and Luke. And now they are gearing up to welcome another grandchild to the brood.
"Michael got married to Sarah in Italy back in July. We had a lovely time. They live in Australia and they just told us they're going to be having a baby in April," Daniel told Patrick Kielty on the Late Late Show in October.
"So it's great news. They used to say [the first child] is the wedding night baby - and [the due date] is nine months from the very day!"
