I have my husbands grandmother's name, Helen, she had a brother in Canada, Walter and a brother who settled in Ohio, named William. Can't find how or when they immigrated into US or Canada. Helen and William settled in Ohio but beyond that don't have much info. There was a daughter to Walter named Agnes, who had a son Stephen Any help?

Have you found each of them on a census? What was the year of immigration given on the census sheet?
