Sturt is an uncommon family surname, which may be derived from the Saxon words for "hill-dweller". The surname almost certainly originated in the South-East  of England, where even today its occurrence is highest. At some time in the past, there must have been a significant migration to Southern Australia and the Eastern United States. And it was in Australia that the most famous bearer of the surname, Charles Sturt, made his mark as an explorer, giving his name to Sturt's Desert Pea, Sturt's Desert Rose, Charles Sturt University, Sturt's Desert, Sturt Creek and other places.
As there are only some 700 families in the world bearing the surname Sturt, and probably  as many again with a member whose maiden surname is Sturt, I thought it would be an interesting challenge to see whether we could piece together the whole Sturt family tree.
