No, Jesus Christ the Messiah, the Promised One, the Bright and Morning Star, the Branch of Jesse, the only Begotten Son of God, God the Son, did not have children.
That was not the mission He purposed to accomplish in coming to earth. God came to earth and wrapped Himself in human flesh in order to fulfill the Father's will which was to reconcile all things in heaven and in earth back to Him.
Jesus had a specific purpose to fulfill in His earthly ministry. He had a specific reason for coming to earth. That purpose and reason was to fulfill the Father's will. The Father's will has been revealed throughout the Word of God. His will was to reconcil (bring back into harmony and peace) all things to HIm.
Reconciliation is Christ's purpose for coming, restoring all things from the chaotic state that was brought into the world through the sin of man.
The word states that through Jesus' redemptive work all who believe in Him and His sacrificial atonement are no longer in a state of chaos and rebellion but have been restored to the original state of mankind before sin and now have peace with God.
The following scripture speaks to us clearly the concept of reconciliation through Jesus Christ.
"Since we have now been justified by his blood, how much more shall we be saved from God’s wrath through him! For if, when we were God’s enemies, we were reconciled to him through the death of his Son, how much more, having been reconciled, shall we be saved through his life! Not only is this so, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation." Romans 5:9-11
So you see, Jesus' purpose to come to earth in the form of man was not to get married and have a family. While marriage is an honorable sacrament it was not the calling the Lord Jesus had upon His life to fulfill.
To speculate on things that have no valid claims is to discredit the purpose of Christ's coming and to deemphasize the redemptive work accomplished through Him.
