The Frau v. Knyphausen bit actually stays until 1754, but the change in 1748 is from "Brüderstrasse" to "behind Brüderstrasse at the waterside", which fits a 1747 sale perfectly. So the question is, did she acquire a different house "behind Brüderstrasse etc" or is that supposed to be a synonym for the Jägerhof, which is on the other side of the water plus a block over and could have been called just that?
