A young girl got it from poultry, her mother, caring for her, got it, but also may have been exposed to poultry. Her mother's sister had no known poultry exposure, but cared for the mother. All three died. You are correct, that is the first recorded instance of h2h transmission. In that instance, no health care workers got the illness.
Remember that the Indonesian fellow in the CFR transcripts said that the nine people who died there were, and I quote, "only the tip of the iceberg". He admitted that they had no idea about the number of humans who had it or had died.
