Well, then, I guess Matthew is mistaken when he says "the genealogy of Jesus Christ"? And, I guess, according to you, Luke is also mistaken since he doesn't mention Mary in Jesus's lineage.
Obviously, Matthew did show the lineage of Jesus through Joseph. And, again obviously, neither Matthew nor his Inspirer had a problem with Jechoniah/Jechonias being in the lineage of Jesus. So, there must be an explanation.
Fortunately, for the legalists, there is a known (actually more than one) explanation. But, even if the explanation weren't known, there still had to be an explanation.
You have to believe that, when God Promised David that his descendants would sit on the throne forever, that He knew what would happen with Jechonias and had already instituted the plan.
Jehoiakim had a son, Jechonias, whose first son, Salathiel, had a right to the throne of Israel but who had no children. But Jechonias apparently took another wife who had a son, Pedaiah, by another marriage, and he had a son, Zerubbabel. By Levirate custom, Zerubbabel, has no blood line connection to Jechonias, for he has no blood relationship with Salathiel. But, he is in the blood line of David through his grandmother Neri. So, yes, Jesus is descended through Joseph and Mary, and it just so happens that His right to the throne of Israel, as the last king of Israel, traces through both Joseph and Mary - God's way of making sure there is no legitimate claim that Jesus does not have a legal right to the throne of David.

The words of Jeremiah....
Jer 36:30 Therefore thus saith the LORD of Jehoiakim king of Judah; He shall have none to sit upon the throne of David: and his dead body shall be cast out in the day to the heat, and in the night to the frost.
If JOSEPH is the true father of Jesus then the Holy Spirit is not! That makes Jesus just another man.
The geneology in LUKE is of Mary, even the jews of that time believed it.
