{geni:about_me} According to Julius Muller, genealogist:

"I do not give up on Ballenbergers. In Natl. archive Prague I found circumcision book of Liten (hometown of Anna née Bondi). My former intention was to find marriage records of Liten but those are unavailable.

In circumcision book there is one son recorded: Jakob son of Samuel Ballenberger of Pristoupim, circumcised April 2, 1816. I also checked Liten birth records to get more but surprisingly, such record in not there. We are lucky anyway.
Reference:
Liten circumcision book 1781-1838, HBMa 1056 http://badatelna.eu/reprodukce/?fondId=1073&za...&reproId=3694486

Liten birth records 1804-1822, HBMa 1051

Pristoupim is town near Cesky Brod, E of Prague, I will check what can be found there."

Burial record is on Jewishgen.org. Says he was 94 when he died, so maybe his birth date is earlier than 1816
