I see the name Birgitte Simonsen. Simonsen is one of the old-time Hackensack names, going way way back, maybe even to Colonial times. The Simonsen estate was torn down to build the MainOak apartments, at Main and Oak Streets in the northern Fairmount Section.
The last known Simonsen in Hackensack was an elderly woman living in a house on the eastern block or so of Willow Ave, in the 1980s. I wonder if Birgitte is a descendant.
