There's been some speculation that Jesus was married. Some of the speculation is in a book "Was Jesus Married?: The Distortion of Sexuality in the Christian Tradition" by William E. Phipps.
In a nutshell, in those days it was the norm for parents to arrange marriages for their kids at an early age. It would have been unusual for him NOT to have been married. The first miracle was Jesus turning water into wine at a wedding. The speculation is that the wedding was HIS wedding. Later in the Gospel mention is made of the "disciple whom Jesus loved". The speculation was that this was Jesus's son.
After the crucifiction, Jesus's family was supposed to have been smuggled off to France
Isaiah 53:8 disagrees:
By oppression and judgment he was taken away. And who can speak of his descendants? For he was cut off from the land of the living; for the transgression of my people he was stricken.
The "disciple whom Jesus loved" was John, his brother.
Not that knowing the truth will ever stop people from making stuff up.
