1.Tooley could be a corruption of St.Olaf,that is the derivation given for Tooley Street in London. 2.Tooley appears as a part of place names around Holmfirth in West Yorkshire, England.The derivation of that is from the Anglo-Saxon "tolle" and "haw" which I amtold means lookout place. 3.Tooley could be a Danish personal name. Most Tooleys in England appear to be found in East Anglia and the eastern counties.That was the part of the country known as the "Danelaw" in the 10th and 11th centuries[I am not too precise about dates.] 4.In 1992,there were no Tooleys listed in the Dublin telephone directory.One would have thought that if the name had been of Irish origin there would have been some.The Boston,MA,directory yielded one Tooley in 1989.One would have thought that given Irish emmigration to the eastern USA ther would have been more.
