This is a trend that has been going on.
Ireland has been in, and everyone wants an "Irish" name. Names such as
Caitlin,
Brayden,
Teagan,
Erin, and others are thought to be "Irish" but are either not used there, or have are not etymologically connected to
Ireland. They are used by people who have less than an ounce of Irish blood in them, to fit into the trend.
Does this make sense?
