Hi Ian,
I do have some bits of information about William and also about some earlier Lees. I found all this out earlier in the year, but it has, to put it mildly, been one of those years, so I haven't been doing much more than glance at Rootschat, without having time to put the information together into a coherent reply. I'll dig it out and send it on. However, I do have to hand Thomas Todd's will of 1872, which I managed to get through the Leeds probate office. I assume Thomas was a tenant farmer as there is no reference to the land. The executors, Thomas Lee and Joseph Todd, Thomas's son, are told to sell all the stock and household goods to pay the various legacies. His children each get £50 and "my grandson William Lee son of the said Thomas Lee the sum of thirty pounds." So that's pretty clear.
Will be back in touch,
Mag
