Siaulia

documented in Livonian Chronicle for the year 1236
and in 1358 (?) as Saule
not found in Das Rigische Schuldbuch (1286-1352) index - Saule, Savle, Sh-, Siaul*, Soule, Sovle; closest found = Saluce, Siveke

Wickenden has: Shala, Shalai (Shalaeva, crazy), Shavlyga (given name), Savlii (var. of Savel, Rus. of Saul), Shila/o (awl), not as a placename.

Saule means sun, also refers to the sun goddess who was either Ausrine's mother, or her rival for the love of the moon god. So Ausrine of Saule may be presumptuous?
