While the family at the center of Everybody Loves Raymond might be a little larger than those seen in many other family sitcoms, their connections aren’t too hard to draw out. Everybody Loves Raymond was a huge hit when the family sitcom originally aired from 1996 to 2005. The show followed the trials and tribulations of the titular Ray Barone, a long-suffering sports journalist married to the demanding Debra. In classic sitcom fashion, Ray was constantly harangued by his wife, his over-involved parents Frank and Marie, his oafish brother Robert, and his three children.
