Elizabeth DAILEY married Thomas JONES a convict who arrived in 1802 on Perseus, not the Thomas JONES who arrived in 1788 on the Alexander
Elizabeth Jones, Free Settler "Kitty" 1792
Thomas JONES the first fleet convict did marry someone and have 1 child
[Thomas Jones [Convict "Alexander" 1788] Thomas Jones [Convict "Alexander" 1788]]
