Thanks @chrisgermany. I appreciate your answer. I just want you to know that it made me feel much better. I have not let these people back in my life. My dad is his own person and has to make decisions for himself. He decided he wanted to meet my sister for his birthday. I told him that is his choice but that he has to respect my decision that they are absolutely NOT allowed in my home - not inside, not outside, nowhere near us actually. I also told him that while he does live in my home and I am glad that he does live in my home, I would appreciate it if he did not disclose our home address to my biological sister and biological mother. I told him I have plenty of good reasons for that. He went to dinner with my sister and my mother for his birthday. He said they basically were just looking for money; sister needs money to go back to school and fix up her house, mother needs money to pay for medical bills apparently. He said he had a hard time believing any of what they were saying and that it seemed like they were shocked and not interested once he told them he has no money, no income coming in, no savings and lives with me. My sister and mother of course chose to go to the most expensive restaurant in town - and of course they had no money to pay for their bill. So he paid over $400 for the meal. He has not heard from them since - not a peep. I guess some people never change. And I hope we never hear from them again.
