My g-grandmother was born in Italy though her father was of Swiss & French decent. She came to the U.S. through Ellis Island in the 1920's. Two of her brothers came in 1903, one settled in Manhattan and the other Brooklyn. The brother who settled in Brooklyn had a bunch of children, some born in Italy, but they all changed the spelling of their last name, dropping the "E" at the end of their name! Looking at the majority of Ferrier's that posted to this board, the name "Ferrier" has Scottish roots.
My Ferriere's originated in Benancon France (late 1600's)and went to Geneva Switzerland into the early 1800's. My direct ancestor lived in London England, was a war emissary in Tunis and upon retirement went to Naples Italy.
I just wanted to let those "non Scottish" Ferrier's know that, by adding a vowel to the end of the name, you may have other options : ) Kathy
