Highlighting the Koehls

I'd like to feature a family on my husband's side for a change. Researching his ancestors is quite different from researching my own. Most of my families are Southern and came over from the British Isles no later than the mid-18th century. My husband's family lines come from Germany, Italy, and Romania and the earliest immigrants among those apparently date to the mid-19th century. They immigrated to New York, New Jersey, and Canada. As a result, I have to learn to use a different set of resources.

Here is what I have been able to learn about the family of Julius Henry Koehl and Josephine Lochner, my husband Stuart's great-great grandparents:

This information is based primarily on census information and the Social Security Death Index. If you are related to this family or researching it, I would love to share information with you. If you are familiar with methods and resources for researching these areas, I would welcome any advice.
