A man carried out indecent assaults on two of his daughters when they were moved to a care home, Tullamore Circuit Court has heard.
Patrick O'Donoghue, Ballygaddy, Kilcolman, Birr, now aged 74, began abusing the girls when they were aged four and two.
The abuse began in 1970 and continued for ten years.
A sentencing hearing was told the girls' mother had been taken into psychiatric care following the birth of her fourth child.
The abuse began in the family home and continued at a care home where the victims were sent.
Judge Keenan Johnson said he will sentence O'Donoghue on 25 November.
However as it will be a custodial sentence, he placed O'Donoghue into immediate custody.
