Mary has several obituaries which only mention two daughters and a son living - Wm in WA. The two daughters would have both been born in Aus as their ages on their respective marriage registration indicate they were born c1858 and c1861 and their births were not registered or the registrations did not reach the SA registry.
Ah...Daughter Mary's obituary states she was born Wirrabara 30 May 1861
http://www.rootschat.com/links/0grq/One of Mary's obituaries indicates they also lived in Victoria and I note the death of a Richard
KRONCKE born Germany in 1865. He was aged 33 years. Parents unknown. Of course he may be no relation but is the only KRONCKE listed on the early indexes in that state. The is a notice in a Vic Govt Gazette in 1867 regarding his estate at Digby.
A few relevant snippets...and there are many more...

http://www.rootschat.com/links/0grv/Are you basing your information
They were accompanied by sons Richard b. 1832, Johann Heinrich b. 1836 and 1 or 2 unnamed daughters all born in Germany
solely on the information found on the shipping records or do you have another source of information? I can see no marriage or death for the unknown KRONCKE dau of Carl...and there aren't many records to search of that name in Aus
.
