Hi Gary,
I have been trying to trace some Le Lacheurs that went out to Australia in the mid-late 1800s.
If you have a look at my family website
http://brehaut1956.tribalpages.com/tribe/browse?userid=breha...and click on the Le Lacheur surname, select 1817 Helier and away you go. His daughter Ellen was my great grand-mother.
Hope you have information on the Le Lacheur family that went to Australia.
