First SA Lithuanians

Research conducted by Jonas Vanagas reveals that the first Lithuanians to SA were the Varno family, consisting of parents a son and two daughters. They arrived on the ship the Skjold in a group of 275 from Prussia. The family settled at Lobethal in the Adelaide Hills. I have searched the BDM's for any mention of the Varno family and have found none. The shipping list available online also reveals no Varno family for the ship the Skjold. I have no doubt that Vanagas found some reference to the Varno family but as yet have not been able to trace the source. I have tried variations on the spelling of the name also with no luck. Did they move interstate? anglicise their name? I won't give up seeking though, there must be a reference.
