My Mysterious Uncle Clifford

All my years growing up I've known my uncle Clifford, never once thinking anything was strange about him. But when I went to university and studying history, that changed. My class was given an assignment to research our family history. It was to give us a taste of researching basic history. Sounded boring to me as my family weren't of anything special in history. I done my father's side and it was the usual basic boring history of most families. I then done my mother's side and had a similar outcome. Only later did I realize there was something missing. I was writing up my final report and decided to list a family tree joining both sides together. At first it didn't dawn on me, but there was someone missing. Clifford wasn't on either side of the family, not related to my mother or my father. But he was always called uncle and I'd always thought he was my uncle. So, I asked how Clifford was related to the family. I was finally told he was my mother's half-brother and my father, the man I thought was my father wasn't. But he was the father of my 2 siblings, Clifford hadn't known my mother was his half-sister and they started a relationship, I was the result. Only then was it discovered, Clifford never married and done very well career wise. Supporting my family financially and that solved another riddle in my life. My father never had high paying jobs and we were living very well and had a really nice home, I thought we must've inherited money to provide everything we had. But it was Clifford, he supported us all the time and became my uncle instead of my father.
