Sheriff's officials say 61-year-old Donald Dunakin and 47-year-old Ina Medina of Talmadge were taken into custody Thursday night and each booked in county jail in lieu of $250,000 bail.
The suspects face multiple felony charges, including sodomy, continuous sexual abuse of a child, lewd act with a child, oral copulation of a child, penetration with a foreign object and torture.
Officials say sheriff's detectives began investigating the case on Wednesday when they were contacted by county Child Protective Services.
Officials allege the children were ages 3 to 16 when they were abused by the suspects, who have lived together in the Ukiah area for about 30 years.
