<P> JJ is married to Detective William "Will" LaMontagne . They have two sons Henry and Michael . As of season 13 she and Matt Simmons are the only members of the BAU who are married with children . </P> <P> Prior to her courtship and marriage to Will, JJ displayed little interest in dating . She once went on a date with Spencer Reid to a Washington Redskins game, but little came of it romantically, although the two became very good friends . In the season 2 episode "Jones", JJ first meets William "Will" LaMontagne, Jr. a NOPD detective whom the team worked with while in New Orleans after a serial killer presumed dead following Hurricane Katrina resurfaces . It is revealed the following season that he and JJ had been seeing each other for the past year but kept it a secret as she wanted to keep her personal life away from the prying eyes of her colleagues, which Will initially misunderstood as her being ashamed of their relationship . When she finally reveals their relationship by kissing him goodbye in her office with the blinds open, it is apparent that her colleagues already knew about them . </P> <P> In "The Crossing", JJ told Will that she was pregnant with his child . He later asked her to marry him, and indicated that he was willing to give up his detective's shield in order to help take care of the baby and allow JJ to continue to do her job, though he was worried about her safety and the safety of their child . JJ later told Hotch she had found a temporary replacement for the duration of her maternity leave, and soon after gave birth to a baby boy named Henry . Will transfers to the MPDC, and the family live together in Washington . In later seasons, toddler Henry is portrayed by actress A.J. Cook's real - life son Mekhai Andersen . JJ and Will named Reid and Technical Analyst Penelope Garcia as Henry's godparents . When JJ returned from maternity leave, she and Will had exchanged rings with Henry's birthstone, but did not seem to be officially engaged, as she wore her ring on her right hand, not the left . In the season seven finale, JJ tearfully asked Will to propose to her again, and they married the following evening in a small ceremony in David Rossi's backyard . </P> <P> JJ is very loyal to her family and friends, as well as very protective . She is also known to be a crack shot . This was demonstrated in many episodes such as "Nanny Dearest" by shooting a fleeing suspect in the head at a faraway distance . In "Revelations", she killed numerous flesh eating dogs in a dark barn . In "Penelope", she kills Garcia's attacker by shooting him directly between the eyes precisely as he turns around to find JJ behind him . Despite her petite frame, she is very athletic and has shown herself to be able to hold her own even if disarmed . In the season 7 finale, she manages to physically fight off a stronger and taller suspect who had tried to kill Will and took their son Henry hostage . She is best friends with Spencer (and is the only one who calls him "Spence"), Penelope, and Emily . </P>
