Saul's first and possibly only wife could not have been the Ahinoam mentioned in connection with Abigail, because she would have been at least 70 when he took her to wife--definitely too old to bear him a child without it being remarked as a miracle. The Bible says Saul became king in the prime of life, and he ruled Israel 40 years before dying on the battlefield. Two years into his reign, his son Jonathan ran a military operation--Jonathan must have been over 18 then. Thus King Saul had to have been about 35 when he became king, and his wife Ahinoam was then at least 30 (if 13 when she had Jonathan). David had to have been in his early twenties when he fled Saul, because he mucked about the Judean desert and Philistia a few years before Saul died at age 75 and David became king at age 30(Jonathan would have died at approximately 55, and Ahinoam would have been at least 70.) David was 30 when he became king of Judah and his sons were born after that. Of course David inherited Saul's harem eventually, but the oriental harem included all women of the family, not just sex partners.
