Olmstead Lane in Huntsbury – nothing on library website and it is possibly because it is too new or because it is a private lane. Probably named after Olmstead Green in England which would be in keeping with the general theme of naming streets after places in England. When googling I found a Frederick Law Olmstead who was one of the creators of Central Park in New York.
Another street that I didn’t walk as it looked like a private driveway and google vehicle avoided it as well. Only 6 houses here built between 2000 and 2014.
