Do I(40M) allow family that kicked me out at 18 back into my life, wife is eager to know them but I do not know how I feel.

I have never spoken of my family to my wife or my children. They know I was kicked out at 18 but not the reasons why. I have never spoken to my family in 22 years. I was once told by my father that I was not his and he was just raising me out of obligation. I was treated poorly by them, I had to work my own jobs since I was 16 and purchase my own food. <br><br>I am a successful businessman now, own 3 fast food franchises, 2 convenience stores, one restaurant and a gas station. We live in a large 7 bedroom home on 14 acres. My wife knows how hard it was for me to get to where I am now, she met me when I was working three jobs and going to school. I am pretty sure she would never allow them back in my life but that is not really the issue here.<br><br>I was in a great mood when I arrived at the restaurant yesterday, which we do every Sunday, to find a young woman there about 22. I asked one of my managers if I needed to call the police since she was in the employee area. Natalie, is the name that my manager gave me, said she was my niece and wanted to meet me. Here is where I am confused, my sister does not have a daughter that old, she was about 4 when I left, my youngest sister was about 10. This means that my sister would have been about 16 when she had this girl. I am pretty sure my parents would have shipped her out to have the baby and give it up for adoption. <br><br>Natalie told me that she found out about me about five years ago and last year she found where I lived. Upon learning that I was a business owner she felt that finding me might not end so badly to her. She said that she had a great aunt that had raised her and she had a good life. While I was talking to her I noticed that she looked a lot like my father. I asked her what her father's name was and she looked down and started to cry. She said it was my father. She told me her mother was a girl that had babysat for my parents when I still lived there. She was 16 when she got pregnant, her parents threw her out and she moved across country and when she turned 18 my father started sending her money, she also had help from her aunt. Natalie said she only wanted to get to know me and my family, she didn't want any money. After talking for about an hour I gave her a bunch of gift cards to my businesses, told her she could eat for free at any of them and I would call her next week. I told her that I did not know if I would allow her to meet my family. She was extremely happy that I would even talk to her.<br><br>This has been eating at me since yesterday. I do not even know if I should tell my family I have a new niece. I do not know if I am ready to even talk to them again. I really do not know what I am feeling. I do know that I want to see her again. But I do not want my parents involved if I do. <br><br>Am I being immature not wanting to contact them? I do not even know if they are still in the same house.<br><br>Edit: It is me again. I just wanted to thank everyone for the advice, I have decided to talk to my wife tonight. I will tell her everything that I can remember, at the very least she needs to know what to tell my children. I have decided to talk to a lawyer before I contact my sister. <br><br>As for those that feel that my parents deserve a second chance, that is your opinion and I respect it. I am probably not going to contact them again. From reading the comments I am more convinced that even if they do they deserve it, I do not feel I am ready to give it to them. <br><br>I have thought about what some of you have said about generational trauma. It makes a lot of sense to me now. My mother created a toxic environment and I felt that was the way a family was supposed to be so I thought that I was creating a normal environment for my children. <br><br>Thank you for all the advice, I now have a better view of what I need to do going forward.
