Hello, Someone looked up the following names for me in the "New Dictionary of American Family Names": " Sandridge - it is not listed. However, I did find this: Sandidge (Eng) One who came from Sandridge (sandy ridge), in Devonshire. So perhaps, the name could have been changed at sometime for a more familiar sound. Higginbotham, Higginbotan, Higginbottom, Higginbothom, Higginbotham (Eng) Dweller in or near the valley owned by Higgin; dweller in the valley of oak trees: or in the low place enclosed by a hedge."
