I know that Wikepedia where you got your information says that the Edict of Expulsion ended in 1834 but in effect there were two different times that it ended. One was on Dec. 16, 1958 when the second Vatican Council formally and symbolically ended it and the second one was on March 31, 1992-500 years from when it officially started in Spain that King Juan Carlos signed the official document ending it. This was signed in a temple in Los Angeles, California.
I don't doubt that you have some knowledge of this event but I am Sephardic and have done research on my family and this topic for many years. Hope this information is helpful to you.
