Just returned from a trip to Ireland, both the Republic of and Northern Ireland. Teddlie is not an Irish name, whether it is spelled Teddlie, Tedley or Tedlie. There are records of Tedlies and Tedleys in Northern Ireland which means that most likely they are of Scottish or British origin. While our ancestor is reported to have sailed from Cork in the Republic of Ireland, so did over a million other people during the mirgration periods. I was unable to find a record of William James Tedley's emigration from Cork in the Migration database at the Ulster American Park.
