Helfrich/Steiner Family's of St Louis, Missouri

Hello
I am resarching my family tree. I have some fact about both sides
On my mother side Gertrude Steiner we go back to Switzerland. On my father side we go back to Ill.and maybe into Canada. My father had a sister Helen and two brother John and Harold. If anyone has information about these people I would truly appreicate any help.

Thank you Earl Helfrich
