The National Gazetteer of Great Britain and Ireland - 1868
"ALLERTON, a township in the parish of Childwall, hundred of West Derby, in the county palatine of Lancaster, 4 miles to the S.E. of Liverpool. It is near the river Mersey. Allerton Oak is an ancient tree standing on a farm in this parish. Here too is the rude monument called Calder Stones, considered by some to be Druidical. Urns of clay, with human bones, have been dug up near it. Allerton Hall was once the seat of William Roscoe, the historian, author of the Lives of Lorenzo de Medici and Leo X. Allerton Priory is another seat here."
