Before the discovery of this document the only information I had regarding the Jacobson family prior to John gaining his citizenship, was the oral tradition related to me in a phone conversation by Victoria Jacobson.

In this document we find only our 2nd reference to David (the other in the 1916 directory), and he is boarding, along with brother John, in the home of Jacob Jacobson - whom I can only assume is their father (or step-father). I think that Jacob's employment at a silver company will also prove helpful in validating later references.
