Hiya, Glad things seem to be panning out.. SA deaths do not list parents,,,the marriage may list fathers name (which would help) but my CD is too scratched to run,,,maybe someone else will check the marriage 1844 for you..
I did find 2 deaths which dates and everything fit.. Elizabeth JONES,,W,,died 1-1-1914 Adelaide,aged 89yo,,relative DH William JONES
William JONES died 30-12-1888 Kapunda aged 72yo,,relative Son J H JONES. (This was the only WIlliam JONES dying at Kapunda within right dates...
Now for the Bowden,,In trying to help confirm Magaretta's parentage I checked for BOWDEN deaths in SA and nothing to fit BUT I noticed a mention of BAWDEN so I checked and wooo hooo. Elizabeth Ann BAWDEN died 1878 Moonta aged 39yo Relative Husband John BAWDEN. Going on that I checked the 1871 Census and found this BAWDEN family in Cornwall!!! John b.1841 Steilor Cornwall.(Miner) Elizabeth Ann b.1839 Crowan Cornwall. Eliza Jane b.1863 Phillick Cornwall. John King b.1869 Gwinear Cornwall. Mary Jenkin b.1865 Cramborne Cornwall. Susan Ann b.1870 Gwinear Cornwall. Walter b.1867 Gwinear Cornwall.
Of course Margaret and Ellen are not listed as born after 1871 BUT I found births for a Margaret A 1873 Redruth (which is registration district for the above 1871 census) and 2 notices for an Ellen both in 1875 Redruth..one in June and other in December.
SO going along the lines that your Margaretta (who may be Margaret A) said she was born in Cornwall,,,it may very well be your Margarets family....
I will go and check other stuff and see if anything else matches up Kellie
