Sheila Jameson was the wife of Alex Jameson, the Chief Financial Officer of Farrow-Marshall, an aeronautics firm that had come under the control of the Goa'uld-infiltrated Trust. When Alex Jameson disappeared and a dead Jaffa, killed in a hit-and-run accident, turned up near Farrow-Marshall's plant in Edison, Virginia, SG-1 was called in to investigate. Sheila met with Daniel and reported that her husband's behavior had changed six months earlier. Suspecting an affair, she had hired a private investigator, but after taking some initial pictures, the investigator quit two days later, visibly shaken, and he had returned her money, urging her to drop the investigation. The investigator's pictures provided a lead which eventually revealed that Alex Jameson had been taken as a Goa'uld host and had been captured by Gerak in his attempt to locate Ba'al on Earth.
