The PSNI said a family of eight have turned up after an appeal to locate them.
The PSNI traced the missing family of John Kelly and Melissa Teague, and their six children, to the Republic of Ireland.
The children are aged between five years and nine months old and originally from Co Longford.
They had last been seen in the Ballymartin area near Kilkeel on Wednesday, according to the PSNI, and an appeal was issued this morning to locate them.
About three hours later, they were accounted for.
They are all safe and well.
The PSNI would not say who had reported them missing.
