Hi Faith,
The key link between the Lees and the Todds is that Thomas Lee, the miller of Ingleton, married Elizabeth Todd, granddaughter of Joseph Todd the tollgate keeper (daughter of his son Thomas, who farmed at Killerby near Ingleton). Thomas and Elizabeth's son Richard Alfred married Harriet Alderson and one of their children was Herbert.
Going back from Thomas is problematic. His parents were John and Isabella Lee, who for some time lived near Wolsingham, in Weardale, and followed the miner/farmer way of life typical of the North Pennines. We have been walking in the area where they lived today, but their former home is somewhere underneath Tunstall Reservoir. However, It is difficult to find their parents. John seems to have come from the the area round Allenheads just over the Northumberland border, but there were quite a few John Lees.
If you reply to this, I shall then be able to send you a personal message and give you my email address. I have a lot of family photos. Mag
