Great images. I think these are the pic's that were hanging at Wellington Hall (owned by the Squillace family) in the mid-1990's. They must have been moved to HUMC, or perhaps copies of them.
A few observations:
1. "Colonial Home" and "Old Colonial Home" are different angles of same house, and that property is currently Spotless Car Wash. Note the riverbank vegetation. Reportedly that was the oldest house in Bergen County. There is also riverfront vegetation/mud in the Esso gas station picture, but I can't figure out where that was. Perhaps in Teaneck, south side of Cedar Lane ?
2. Passaic & State Looking South is actually looking NORTH. Verify based on width of State St, and old atlases shows a row of tight-packed houses to the north, whereas south of Passaic the houses on State Street were well-spaced and quite grand.
3. The Ed Van Saun home is specifically the NE corner of Park & Passaic. It was torn down to build a gas station, and it is now the parking lot/play area for First Baptist school. The second house (right after it), on Passaic St, was purchased at some point and designated as the missionary house for First Baptist. It was torn down around 1998 and replaced with a modern duplex house with no landscaping, still owned by First Baptist.
