I have traced my family of Crahan's back to Ireland in the early 1800's. The name was spelled Crehan and changed after they came over during the potato famine. Six brothers and sisters of my great, great grandfathers generation traveled to America over a period of years and settled in Fulton, N.Y. It is not clear how or why they ended up in upstate N.Y. As there are no Crahan surnames in Ireland years ago, I am curious if other Crahan's of today have any records or information when there family might have changed thier name. As For my family, Records, including birth, death, baptismal and marriage certificates clearly show that the Ireland born family was spelled Crehan and changed, one by one to Crahan.
I have talked to people in Ireland and when they say the name Crehan, spelled with an E, they pronounce it "Crane". That makes sense for them to have change the spelling, however, it's just a guess.
I would love to hear from other Crahan's! I am willing to share any information I have. Hope to hear from someone soon!
