What is the name origins of the streets in this neighborhood? Fearnley Road and Colbright Road? As well as 1st, 2nd and 3rd Roads. Typically in south Florida the numbered roads come off of a major intersection but these are kind of free floating.

Can someone please verify if this is the Sherbrooke Golf and Country Club? Thank you.
