Can you help?

This page details some outstanding queries that you may be able to help me to resolve.

1. How did the various towns, places, etc. became named Lockwood?

I would be very interested in hearing how the various Lockwood towns and places became to be named. I already know about Lockwood, California, USA, Lockwood Island, Cape Lockwood and Lockwood, Huddersfield, West Riding, Yorkshire, England. if you know the history of any others please let me know.

2. In 1964 and 1965 only, London had a dialling code LOC which was short for Lockwood. Anyone know where this was in London?
