Where they lived in Omaha.
The story so far: we catch sight of these people under George III through a business card fortuitously preserved advertising their prepping of houses for resale. They lived in London, mostly in what is now called Fitzrovia and a bit further north in Camden. The third generation included my great great grandmother, Florence May Schaller, and her family had moved first out west to Hammersmith and then to the US State of Nebraska, where we find them in a US Census for 1870.
In an 1872 we find the patriarch of the Schaller clan, Cornelius Robert, working as an agent for the B&M Railroad. His house is listed in a municipal register as being on the SW corner of California and 19th St.
We find the Schaller clan there for several years (renting, I would guess) until the 1879 guide, which notes that Cornelius Robert is now a Livestock Agent, worked on S. 5th St., near the old UP Bridge, and had moved (and bought, I should think) to the house in which the family is found until the end of their time in Omaha: 522 N. 24th St.
The 1918 map seems to indicate that the house would have been the one labeled 524 N. 19th St.In the 1885 guide we find Cornelius Robert listed as a VP of the Omaha Coal and Produce Co. and as a Real Estate Agent with offices in the Millard Hotel. All of these addresses are underneath something these days: the California one is under Creighton just south of Opus Hall on 19th; the 24th St. address is just south of Deglman Hall nowadays; and the Millard was where the Holland Center sits now.
For those who know Omaha well, here is a Google Maps view of both addresses (that is, it is effectively a shot of Creighton University, which has greatly grown since 1879):
California St., which is a useful landmark for both addresses, has been destroyed and turned into a walking mall running roughly down the center of the campus. In the Google Map reproduced here it is the long thin green line running E-W about one third of the way up from the bottom of the map.
