I have already found puzzles called Einstein (ones so difficult, Einstein wasn’t able to solve) but I’m not sure if they were like this. Is this a name for a particular puzzle exactly like the one above,… or for a puzzle sharing the logical structure of the statements as the above (changing for instance, the names of the colors or perhaps a category – Pets – for another – cars),… or the name for all the puzzles like this one, demanding to match people with properties satisfying a set of logical conditions?
One day, I might try to discover some general method to apply to them but for now, is this man keeping a fish, the one who sold carps to a certain sea-captain who keeping them in a pound in Troutdale, ended to be the one to introduce the first non-native fish species at Oregon state, at 1880?

Google it to have an hint to my answer if we want it, don’t if not.
PS.: I assumed that the first house was the leftmost house of all (and not the rightest) and that the house left to other is an immediate neighbor of the other… these assumptions didn’t lead to any contradiction, although the first assumption probably defines all the solution, and might give to other different, if negated. For sure, it appears to me to be more natural to count houses from left to right, however, the way we drive at the right in my country, the first houses to encounter at right, is the rightest. Resuming, it might be not very clear how we find the “first” house.
