The Cullon/s family is in my ancestry and they are related to the Black family by marriage.

Dennis Cullen was a well-known tombstone carver in Ireland. In some quick research, I was only able to find one Edward Cullen and he died in New York. I am not sure what resources Stephenie Meyer said she used in 2005 to locate an 17th Century English tombstone since internet resources were more limited and she did not leave Arizona in the 3 months it took to write “Twilight.”
