Tithe map of 1847
The Tithe Map of 1847 (above) was actually surveyed in 1845. It shows clearly the Hen & Chicken road (marked in blue), but there is no sign of either Gid Lane or the drive to Froyle Place (I've sketched their approximate locations in green). Further refence to the first Ordnance Survey map (below), dated 1817, shows the Hen & Chicken Hill and traces of a track where the drive to Froyle Place should be.

A closer look at the Upper Froyle end of Gid Lane, by Blunden's Farm, shows the start of a track leading into the meadow, number 166, a large area of just over 41 acres, called Second Park. I've marked the actual bit of the map with a green circle - it shows a possible gate across the track, could this be the origin of Gid Lane - "Gated Lane"?
