WASHINGTON — April 10 is National Siblings Day, and on this Friday, we are sharing photos of celebrities and their siblings to mark the day.

The foundation’s website features letters from U.S. presidents in observance of National Siblings Day, and says it was granted a “Service Mark” in 2007 by the U.S. Patent and Trademark Office.
