William gave you a lot, but I found a bit more. There is a US WW1 draft reg. for Russel Creighton Stewart which shows him as born
July 2, 1878. It says he is a US citizen by father's naturalization before registrar's majority - which should mean his father was naturalized before Russel became an adult. So that tellsme that he would have come to the US with his parents - or at least with his father.
Odd thing - 1920 census shows Russell arrived US 1890, 1930 census says he arrived 1883
AHH - just found death for Russell which shows wife as Hulda so that fits AND shows parents as Alfred Stewart and Mabel West. (you can see this entry at familysearch.org) - free site
