OK, Just a Little More CANTORSOHN / CANTORSON

The children of Eva ROSENTHAL geb. CANTORSON (1820-1897) and Caspar ROSENTHAL include the son Bruno (1854-1909).   From the Hebrew on his gravestone (online on Ralph SALINGER's website), Bruno's Hebrew name was Dov ben Jechezkel.

Baer being a kinnui for Dov (as in Dov Ber), this adds another child who was named for the actual or putative grandfather Baer KANTERSON:

• Eva had Bruno (Dov) ROSENTHAL
• Abraham had Bernhard CANTERSON
• Sara had Bernhard HAMMERSTEIN
• Rahel had Bernhard LAUDON

So far, only Johanna (FALKENHEIM) is not known to have had a son Baer / Dov Ber / Bernhard -- because only one child of Johanna and Salomon FALKENHEIM is known to date:  Jacob FALKENHEIM.

The circumstantial evidence still points to Rahel and Sara (and probably Johanna, too) being sisters of Eva and Abraham.

(And it was fun to know that, in at least one case, the name Caspar (surprisingly common in East and West Prussia in the early 19th century) was associated with the Hebrew name Jechezkel (Ezekiel) (Haskel).)
