THE EARLY YEARS: Brigitte & Siegmund to Dec 1962
Contains pictures of their early years, wedding, and etc. until the move to Levick Street. Doug says Deb and Peter both born in Philly. That sets the date latest for their NY apartment as May, 63. If Brigitte wasn't pregnant then they likely moved to Levick in 1962. (NOTE: for now I just picked a date in between - see also Levick St. Album)
