Something to watch out for with roll 2585858 is that on SOME of the pages, the people to key are in the left-hand column on the left-hand page, but the right-hand column on the right-hand page.
On (thankfully) rare occasions, it may even switch in the middle of a page. (When that happens, it's usually accompanied by a change in the handwriting style).
This can be hard to figure out for this roll, given the difficulty of the handwriting, but the way you can usually know for certain is to look for two people's names above each other in one column, next to one person's name and some other words (such as "Ein", "mit", or an occupation) in the other. The latter is always the person to key, regardless of which column it's in.
