My cousin lived on one of the streets just off Durrant Road in the early 70's - mostly terraces with the odd large house and garden, its mostly the terraces that have gone, worth giving Chesterfield Library a ring as Durrant Road ran down the side of the old Royal Hospital - could it have been a maternity home, Scarsdale Hospital was the site of the old Workhouse, also known as 12a Newbold Rd, is it possibly part of the old workhouse?
I have a few books about old Chesterfield I'll have a look and repost if I find anything
