Ah yes, that Old Chestnut of class systems and perceived propriety must have really shook the Jowett Families image...marrying into a Convict lineage.....But women were a scarcity in colonial Australia....English norms appear to have always married young brides to old men ...perhaps the two factors somewhat explains why there was a considerable age gap between Thomas Jowett & Emilie....?
then.....After Thomas passed Emilie met and married her 2nd husband James Wormald. They established the famous Manly Kiosk on the largest yacht harbour in the Southern Hemisphere - which is now the Royal Queensland Yacht Squadrons Headquarter
However the colonial scandal continued for Emilie's mother Elizabeth ...when two of Emilie's half siblings [from her mothers marriage to her step father William Trindall] chose to marry Kamilaroi women - of aboriginal descent.
Though both those Kamilaroi women were very beautiful and faithful wives who bore many children , including my Grandmother, the colonial mindset caste them out....it wasn't until the 1967 referendum in Australia that aboriginal people were liberated to being legally classified as humans and not just flora and fauna...
Today, in Australia some of those "half -caste" descendants are successful and revered professionals, academics and artisans, not to mention agriculturists and scientists ....Nation Builders
you can read about some of them and the Trindall's in the book "Just Lovely"
