Keeping it inside the family

By keeping it, I mean the wealth, my extended family had one big problem. Of all their numbers (31) there was only two who could breed. I 28 was the only male who was acceptable age wise to marry the only female 23 who could have a child. I'm her cousin twice removed as they call, I live in the UK over here they call me a third cousin. Still able to marry my cousin legally as we're far enough apart relationship wise. My branch of the family isn't as wealthy as they are. But we aren't poor by any stretch of the imagination either. My bride was strictly controlled her branch of the family. Me, I wasn't controlled at all, I've always been free to do whatever I wanted to do. I wasn't interested in marrying my cousin at all, until I first saw her. Then I suddenly changed my mind, I'd always had a vision of what my perfect woman will look like. My cousin was an almost perfect match, except for her hair color that is. Her build, facial features and eye color was a perfect match. She was shy, timid and willing to marry me sight unseen as that's what her family wanted. So, I married her and quickly got her pregnant, she is still shy around strangers. But I've accepted she is my perfect wife, she has given me, three children in the 11 years we've been married. The family numbers keep decreasing now down to just 25 counting our 3 children of which only 5 are under 63. My family of me, my wife and our three children. Incest isn't legally attached to our relationship; we aren't closely related enough. But my wife is still my cousin.
