Looking for Ole Nicolai Larson Røo

Brother of my Grand Mother emigrated in 1884, travelling from Bergen together with his uncle Lars J Bauge (Lewis Boyd) who had visited Norway. I have track of their journey all the way to the arrival at Ellis Island. In 1900 there is a Ole Larsen in Stuntz, Saint Louis, Minnesota. In 1910 there is a Ole Boyd registered in Aurora Ward 7, Kane, Illinois married to Liddie Boyd. Anybody who can give any feedback to my searc, will be highly appreciated
