DeLancey family of NY, PA, etc. (1600s - present)

I am researching the DeLancey family which migrated from France to England in the 1600s, then later to New England, where they were instrumental in settling New Amsterdam (which later was renamed New York).

I am especially interested in any and all decendants of Etienne (Stephen) DeLancey who settled in Pennsylvania, Ohio, Kentucky, Missouri, and California.

Any information would be appreciated. I am willing to share the information that I have.
