The accused man has pleaded not guilty at the Central Criminal Court to 46 counts of indecent assault and rape of the woman.
The offences were alleged to have taken place between January 1965 and June 1975 in two different Donegal houses and a shed at the back of one of those houses.
She had been living with her guardian at the time.
She has told the Central Criminal Court in Dublin that the alleged offences started when she was seven and continued until she completed her Intermediate Certificate in 1975.
The jury of nine men and three women had been considering its verdict for 90 minutes this evening.
Mr Justice Paul Carney took the decision to suspend their deliberations for the evening and they were sent home.
The jury will return tomorrow to continue deliberations.
