Brythonia, Arturus I, died of natural causes at age 70.
Queen Mother Satica, first (and only wife) of Arturus I, alive at 69.
Mada Pendragon, eldest daughter of Arturus, dead at age 29 of illness, no issue.
Her aged (and celibate) husband survived her, and died at age 80.
Queen Aytena, Arturus's second and last daughter, alive at age 39.
Aytena's first husband died at age 69 of natural causes.
Satica, Aytena's eldest daughter, and the only one by her first husband, died at age 20.
Satica's widower is still living, as is their 1 year old daughter, Godgifu of Chester.
Princess Umaxa, heir to the throne of Brythonia, age 8, daughter of Aytena by her second husband, is age 8, betrothed to the 5 year old great-grandson of Comes (formerly Dux) Maximus Artorius of Dyfed (only son of only son of eldest son; thought it was a matrilinear betrothal, but it looks like it's a normal... have to see what happens when they both come of age.)
Rex Amilo Bolgios, Aytena's Galatian second husband, is 32, with a strong claim on the throne of Singidunum (which is much too far away to consider pursuing at this point.)
The Welsh Artorii have a healthy brood (Maximus has 3 sons and 3 daughters, all but the eldest daughter living.) The Cornish Artorii are the hillbilly branch (current king Gerallus I, grandson of Magnus, is 27 and has been married 3 times, twice to aunts, and currently to a cousin. Other than Gerallus, his wife, and his son by wife/aunt #2, the only other surviving member of the clan is his 20 year old spinster sister.)
