Weaving my ancestor’s voices

If this blog is about anything at all, it’s about just how relevant our local history is to what we do, are and feel today. I passionately believe that exploring our collective past can teach us things about the present that help us make sense of, interpret and explain what we see around us.

I’ve been hugely engaged by the level of comment and involvement with the recent discussions about the history of coal mining on Brownhills Common. Through maps, recollections, books and existing evidence we’ve begun to find out more about this vital component of the past Brownhills. This industry shaped the town character, it’s environment and landscape. With that in mind, I think it’s time we united that knowledge with some new technology.

Long-time readers will know that I’ve made Google Earth overlays out of old maps for some time. These enable you to load a map over satellite imagery in Google Earth and fade the map in and out to see fairly accurately where old features were. I’ve now done this with a selection of the 1:2,500 scale Ordnamce Survey plots of the common area I posted last week. These are fun to play with, and help show how and why the landscape of the common is such as it is.

Further, though, I’ve enabled these overlays to be loaded into compatible Garmin GPS devices. If you have a Garmin Oregon, Dakota, Colorado, GPSmap 62 or Edge device or similar modern, colour mapping Garmin device, download these overlays from the links at the bottom of the post, connect your GPS and copy them into the \Garmin\custommaps folder and enable them one at a time from the ‘map setup’ menu on the device after rebooting. That area of the common will now be represented by the old map overlay you selected. They can be flipped, or turned off, at will. They work best at scales olf less than 200 feet.

This, I hope, will enable the fairly precise location of long gone surface features. I will certainly be exploring using the maps. Please be aware that inaccuracy in scans, surveying and the GPS system mean that this isn’t a precision guide – and I bear no responsibility if you fall down an old mineshaft, though I’d love to know the location of it if you do. They’re good enough to help locate stuff that may formerly have been hidden, and I’d certainly expect accuracy to within a few metres.

Here the 1884 overlay is seen in use on a Garmin GPSmap 62s.

If you want a guide to using the overlays in Google Earth, see my past post ‘Mapping the past’ in which the process of loading them and manipulating them is explained in full. The relavant files for this batch are hosted at my Box.Net account and can be downloaded by clicking the following links.

If you use them, please do let me know how you get on, and I am, of course, still open to contributions on the topic as a whole. Happy exploring…

    Hi Bob
    many thanks for your clever overlay..I was going cross-eyed trying to switch from one image to another.
    I wholeheartedly share your views regarding the value of our local history…and I hope that , with the passage of time, a clearer picture of the importance of this part of Bownhills’ local history becomes apparent , fully appreciated and readily accessible to all, near and far.
    with best wishes,
    ….David Evans.

    Great work, Bob! I used to work with MapInfo software. This, among many other things, enabled registration of scanned images to the national grid. I recall doing this with the 1884 and current (about 1995) mapping. There was surprisingly little variance, but in the Brownhills common area the difference on things like property and field boundaries can be up to about 5 metres, with the older mapping generally to the south east of the new. O.S. acknowledges some inaccuracy in current (or at leat recent) mapping in areas of little change as these were not routinely re-surveyed using the latest technology. The worst areas in Walsall borough were only about 5-7 metres out, so your expectation appears about right. Good hunting!

    I’ve been thinking about Engine lane the spinney is mostly a spoil heap is this the pit marked as (Lane pit) on the 1841 diagram? Judging from the shape of the spoil heap the pit head itself must have been at the east end of the spinney where the ground levels off. Directly next to this level area is the mysterious earth banked enclosure which I suspect must be associated with the pit my guess is this was the site of the engine and any buildings etc.
    This link shows roughly the setup I imagine but probably on a lesser scale

    Hi Bob
    Curiouser and curiouser!
    I have been re-reading Gerard Reece’s book this rainy afternoon..A pity that some of the sources are not listed.
    ” Phineus Hussey’s will of 1770s mentions “fire engines” ( in the plural ) at his collieries in Brownhills.” ( page 99, Gerard Reece’s book, Brownhills, a Walk into History) Could there have been more than one hereabouts?..waiting to be re-discovered?
    The fascination continues. Thanks , please, to Andy Dennis and to Jim.
    kind regards
    …David Evans
