Then from the Le'Gaunt you eventually reach the Renderra, which goes to Nathan, who is also an Es'ir, folding back into a different group of Sicarius, and eventually reaches Ace Tyrelyn and Caius Aren (Back to Aren/Rovin ties based on adoption) through marriage, and also goes up to the Frostminds to reach a sister who is a Vekon.

And I think from the Tyrelen we eventually hit the Traven?

And I think the Es'ir and Ikra had a few children together as well.

(Basically, if we keep expanding this tree, we will involved every family ever in 42 history.)
