Last month I came across the My Kerry Ancestors website. Run by Kay Caball, a professional genealogist, it has a great blog all about genealogy in Kerry. One very interesting post concerns a migration of people from north Kerry to Canada.
The post focuses on the book The Kerry Chain, The Limerick Link by Carol McCuaig. This book goes into great detail about emigration from north Kerry over the course of the 19th century.
You can read the blog post by clicking here. More generally, the blog is a great read if you have ancestors from Kerry.
