God did not then, or ever, have a wife and for that matter, neither did Jesus. No matter which conspiracy theory you hear about the Merovingian Dynasty of France, or any other supposed bloodline of Jesus, those theories are just that, theories. Unproven theories. The ideas of people trying to make Jesus seem less than the Son of God that He is. There is no basis of fact for them to stand on. Satan brings this kind of stuff up over and over again to lead people away from the Truth of God and His Son, Jesus Christ.
