There was definitely *almost* a Jane/Jean (nee) Robertson among the 109 passengers on board the Minerva (Captained by James H. Robertson) that arrived in Hobart in 1832!
Jean/Jane Craw was married to Walter Craw and her siblings were Grace Robertson (born about 1802 - will scour the Minerva passenger list for a married name for her), William Robertson (son of James Senior, born in 1807, who traveled with his wife Hanna and daughter Mary), James Robertson (Junior, born 4 June 1814 and sailed on the Minerva) - so the Craw family and the large Robertson family were traveling together... Walter and Jane/Jean had further children (in addition to Euphemia and Agnes) shortly after arriving in Van Dieman's Land in 1832 so this rules out any *liaison* between Jane/Jean (nee) Robertson and 'my' James Robertson.
The 'Caledonian Mercury' of 24th May 1832 states the Minerva sailed with 112 emigrants, yet I only have 109 in the 'full' listing in 'The Colonist' of 5th October 1832... Do I have a missing Jane Robertson unlisted? Was David Robertson born on the ship and his birth registered as soon as they got to New Norfolk? There was plenty of time from the ship landing before David was baptised on 14th October 1832.
Tracking Jane Robertson might be incredibly hard if she is not even listed as a passenger!
What a quest!
