I was born in Heaton St, a few minutes walk from Hockley Brook, and lived there until I was 10 (1959); the other day I set myself the task of finding out where Hockley Brook rises and outfalls and used Astoness Lyn's mapsite:
https://maps.nls.uk/geo/explore/#zoom=18&lat=52.4959&lon=-1.9081&layers=176&b=6
Sadly I ran out of fried egg sandwiches (a delicacy I had a particular taste for as a pupil at Harry Lucas School, partly because they were cheap (1/-, 5p in new money) usually procured from a cafe in Farm St) before completing the task.
I'm guessing the Brook must rise very near Hockley, somewhere (otherwise it would not be called
Hockley Brook), as for the outfall I'm guessing the Tame.
Can anyone throw light on this important topic?
Peg.
