Other places tied to Ferdinand Lassalle in the record
In each of these, a source puts Ferdinand Lassalle and the place in the same dated sentence without stating

a mention is not a presence, and Quo Fuit does not quietly promote one into the other.

How to read this page
Every line above is a dated fact taken from a source, with the sentence it came from and a link
back to it. Nothing is inferred, and a gap in the record is not evidence that someone was elsewhere.
A tag says how the fact is carried by its source: documented a structured,
explicitly dated record, attested a sentence that states the person was there,
mentioned a sentence that ties the person to the place without stating presence.
