Where did the Auditore and Kenway lines merge?

It's well known that Flavia Auditore (1513 - Unknown) is a direct ancestor of William Miles (and therefore the Assassin's Creed present day protagonist Desmond Miles).

Assassin's Creed Revelations: Abstergo Files

We also know that Edward Kenway is the first member of the Kenway line to be in the Assassins:

Edward will be thrown in the middle of the ancient war between Templars and Assassins. He will be trained by them and finally become the first Kenway member of the Assassin Order. He’s the father of Haytham, Connor is therefore Edward’s grandson.

In other words, Edward Kenway is known not to be a descendant of Flavia Auditore. Neither is Ziio, as a native American in the 18th century. So when did the lines merge?

One theory (mine) is that Tessa Kenway is a descendant of the Auditore line, but I haven't read Assassin's Creed: Forsaken and none of my research suggests that there's any evidence to support this. I can't find any earlier reference to William Miles life than this story from 1977.

Is it known when and where the Auditore and Kenway lines merge to create the Miles line?
