Other Niels Stedje children emigrate?

Is there any record of Niels (Nielson) Stedje (son of Niels Andersen Stedje and Christi Oldsdatter) born 11 Jan 1825 emigrating? His half-brother Erik Nielson Stedje emigrated in 1856. I was wondering if he or any of their sisters emigrated also--Onni (b. 1818), Gjertrud (b. 1819), Christi (b. 1823), Guri (b. 1827) Thanks for your help! Lue
