From Buck Wiki, the ultimate Buck Rogers reference

Jennifer is William "Buck" Rogers's fiancee circa 1987 CE.

Rogers brings a picture of her aboard Ranger 3, and later displays it on his living room table in his 25th century New Chicago accommodations; Deering remarks on how beautiful she is, to which Rogers' replies that she was beautiful throughout (BR25: "Planet of the Slave Girls").

In the Old Chicago Shopping Mall, Rogers comes across a woman who had been altered to look and sound like Jennifer (BR25: "A Dream of Jennifer").
