A couple in Texas have discovered the bride was the groom's biological granddaughter.
The couple - who have asked to remain anonymous - made the alarming discover while looking through the 68-year-old' man's photo albums, including pictures of his first wife and their children.
The 24-year-old wife instantly recognised one of them as her estranged father, whom the husband was also never able to get back in touch with when his wifrst wife left him with their kids.
Although his second marriage also ended badly, he won ''several million dollars'' in the lottery two years later, and signed up for a dating website.
As reported by C5 News, he said: ''I just felt strange when I saw her photos. It was like a sense of déjà vu, but at the time I couldn't figure out why she seemed so familiar... [But] if we'd never found out, we would've lived our lives happily together, and us being related shouldn't change that.''
