I've not done any research for about 15 years and haven't got my notes, but I too came across Sparkhall relating to J Forsyth.
As far as I remember, it was a farm and I seem to recall that James (or his wife) was a farm servant.
My memory could have jumped a few generations, but I think the wife's surname was Walkinshaw.
As I said, that's sketchy recall from about 15/20 years ago, so apologies if I've thrown in a red herring.
