I found your Erik Förare with the 2nd as his birthdate in the 1886-1892 household examination record for Luleå domkyrkoforsamling (the same as the stads parish). He stayed there for a while and then moved off to "NB (new book, probably) 2:453. There are multiple books covering the same or almost the same years for this parish. This code probably meant something to the priest. We have to try using trial and error to find Erik again. There is a logic to this. It is necessary to figure out the logic. ;-)
