Mr Gates I have a feeling you maybe able to relate? (get it!!) Father and daughter have child A South Australian woman has given birth to her father's daughter after the couple had sex. John and Jenny Deaves reunited 30 years after Mr Deaves separated from Jenny's mother. Jenny was 31 and, just two weeks after meeting, father and daughter had sex. "John and I are in this relationship as consenting adults," Mrs Deaves told the Nine Network last night. "We are just asking for a little bit of respect and understanding."
