Hess, Cinnamon, Dileva and Relations

My father's line, the Hesses, has already been traced by others to 18th-century Germany. My mother's family names Cinnamon and Thompson come from French-Canada, and I intend to follow the line back a few more generations. My mother's sister married a Dileva, whose family emigrated from Italy fairly recently. Other branches include Mitchell, Marcus and Rubesman, whom I have not yet begun to explore.
Please help! I will be happy to share my results in return.
