In much happier news than what lies below, The Life & Times of Baby Otto Zeplin: Volume One was reviewed by Sarah Morean over at The Daily Crosshatch. Thanks, Sarah!
I was feeling the urge do a little more Baby Otto research today. As I have mentioned previously, I was able to find the Zeplin’s 1900 census records (big link, 1.3 mb), so I know the address of the house where Otto was most likely born in. The problem is that Portland renumbered all of its streets in 1933, so the address I have no longer exists on any modern map. The address I have for the Zeplin house is 388 20th Street. In 1933, all numbered “streets” were changed to “avenues,” so I had a start, but no finish. I was looking at the census records again today and realized something, in all this time, I have never thought to use the other addresses on the same page as reference. The first street listed on the census page is Thurman St. then 20th St. where the Zeplin house was and then Upshur St. Thurman and Upshur are consecutive streets in NW Portland, so I could deduce that the Zeplin house was on what is now NW 20th Avenue, between Thurman and Upshur Streets. I took a look at a map before I left, so I knew what to expect, but I decided to bike over and take some pictures anyways.

This sidewalk is the closest thing to “20th Avenue” that exists between Thurman and Upshur. I am standing on 20th and Upshur, the street on the other side of the chain-link fence is Thurman.

This is taken from the sidewalk underneath the overpass, possibly where the Zeplin family once resided.

This area of Portland is, and has been for a while, very industrial, but I was able to find little pockets of what once was. About two blocks from the overpass photo is St. Patrick’s Catholic Church, built in 1889. The Zeplins were German, so there is little chance that they were Catholic, otherwise I might have stopped in for a visit to see if they had any dusty shelves full of church records I could pore through. And about four blocks in the opposite direction was a single block full of houses, all obviously built in the early-1900s, amidst nothing but warehouses as far as the eye could see. One was even for sale, and advertised as being built in 1903, so I snapped a few pictures for reference.
I took another look at Emma and the kids’ immigration records too and noticed that the address listed for Peter, already in Portland, was 635 Thurman St. If you have downloaded the above census record, you’ll notice that 635 Thurman is the first record, the Eggerts. So it’s possible that Peter had been living with or renting from the Eggerts during his solo time in the U.S. You may also notice that the Eggerts had a 21 year old son named Otto. It’s possible it was just a popular German name at the time, but I sort of like to think that Otto Eggert had such an effect on Peter and Emma that they chose to name their own son after him.
