With the onset of World War II, two of J.B's four sons were sent overseas.  While John Morin did not return, R. "Russell" Morin returned with a passion to expand his father's business.  Russell became the sole owner of the diner after buying out his two brothers.  He immediately began to expand by catering off-premise functions and moving the small diner to where it now resides at 16 South Main Street in Attleboro.

With business booming Russell continued to expand the business buying the adjoining buildings, to increase both the kitchen and seating areas. His two sons quickly learned the trade, and after attending Cornell University and serving in the U.S Army they also returned with an interest in further expanding the family business.                                                                                                                                                     
Today, William Morin owns and operates the restaurant, now known as Morin's Hometown Bar & Grille. R. Russell Morin Jr. owns "Fine Catering by Russell Morin"  and the fourth generation is actively involved.
