The family seems to have originated in Devon, England where there are 16C and 17C names including: Angleess Shabbrooke, Christopher Sheobrooke, Grace Shebbrooke, James Shabrook, John Shibroke, and Robert Shaubrocke.
The name Shobrooke and its variations, such as; Shoobroke, Shoobrooke, and Shobrocke, is also relatively common in Devon with a Richard Shobrooke being found as early as 1575.
The most likely origin is that the various names all originated from the village of Shobrooke, in Devon which is only 5 miles north-west of the port of Exeter.
