This is the family tree of House Suth. Note the intermarriages with other Houses: Sardian’s grandmother came from House Imago; his wife from the Imperial House; his mother either from another House or, possibly, from a different lineage within House Suth; and his sister was given to House Aurum
Note also the presence of the Second Lineage headed by Spinel. House Suth has a third lineage but this is not shown.
Of interest is the complexity of the marumaga, or half-blood, members of Carnelian’s household: Crail is Sardian’s half-brother; Brin and Fey his half-sisters. Carnelian has three half-brothers by different mothers: Grane, Keal and Tain. While Grane’s mother was already a member of the household, Ebeny came directly from the flesh tithe.
