Ukko is related to Kishor and are half-brothers. Paiva is Ukko's daughter and Kishor's niece.
Riona is sisters with Frejya. Polly's girl is related to them in some kind of way. Riona has a daughter, Sorcha, Frejya is going to have a yearling. Sorcha and Frejya's yearling are cousins. Polly's yearling will be their cousin???
Sorcha is Kishor's daughter.. (Still need Polly to confirm that 100%), so Sorcha is also Ukko's niece, and Paiva's cousin..????
