Liddell Water is a river running through southern Scotland and northern England, for much of its course forming the border between the two countries, and was formerly one of the boundaries of the Debatable Lands.
Liddell Water's source is beneath Peel Fell in Roxburgshire, in the Scottish Borders, where it is formed by the confluence of Caddroun Burn, Wormscleuch Burn and Peel Burn (burn is the Scots term for a stream). Soon afterwards, the nascent Liddell Water is fed by Dawston Burn near the village of Saughtree.
The river continues to pick up tributaries as it follows its southwesterly course, which takes it through the village of Newcastleton (also known as Copshaw Holm) to that of Kershopefoot, where the burn begins to mark the Anglo-Scottish border. 
Liddell Waters then flows into the River Esk at Willow Pool, beneath the former timber castle at Liddell Strength near Carwinley, Cumbria.
According to the story that has been handed down generation after generation...Long, long, long ago far away in Ireland there was a terrible flood destroying everything surrounding Liddell river. After the flood some children found a baby near the Liddell River. No trace of the baby's parents or any relative. The children took the baby home to their parents they raised the child up and since he had no name or identity they gave him the name, Liddell. Since they found him at the river, like the biblical story they called him Moses, Moses Liddell.
           Moses grew up, married and had a family along the Liddell river. They family grew and some came to America. From this baby alone at the Liddell River...this move that the Liddells in America are descendants of....
