Irish Name Locator: 11th to 16th Centuries
On surname lists, it really pays to take the time to go down the whole thing carefully!
Often names have been spelled many ways, and one needs to play with them phonetically in order not to miss one's goal
due to "odd" spellings!
Also, don't forget to look through the Mc's, Mac's, O's... and also, if you have a prefix, check for those who've dropped it!
To do the "quick and dirty",
you may use Surname Helper to Search Surnames on our Site
but don't forget to take time and browse as well!
