OK, went down the rabbit hole looking for info on M.W. De Laubenfels, a zoologist from Stanford whose specialty was sponges, but who also published one of the first papers positing that the extinction of the (non-avian) dinosaurs might have been the result of an asteroid strike (1956).
Anyway. . . his grandfather was one Capt. John de Laubenfels (né Laubenfels with out ‘de’), whose handwritten biography appears on his findadeath page, where he mentions his birth city. He also says that his daughter is a baroness. Maybe she is, maybe not, but if he isn’t part of some peerage, then who now much is accurate. I’ll take on faith that he was a captain in the Union army, but who knows? Adding to my suspicion about how accurate this is comes from the notification of his death (also on findagrave), where it says " his career had been a most chequered and eventful one. Beyond this he seldom spoke." So, rather mum about his past.
Anyway (again). . . a Google search for this phantom city brings up exactly one citation–the aforementioned findagrave entry.
So. . . anyone wanna tackle this?
