Beth now it get's complicated Al was married five times Beth was his first and thought he had died when in Viatnam. In the last episode Sam leaped back and told Beth that Al was alive they stayed married and had five children.
Donna is Sam's wife and as far as i know is in two episode the secomd was episode one season four where Sam and Al trade place and he leaps back and remembers he is married. The first is the second episode of season one and Al leaps in to a Collage proffeser at Donna's collage and helps her reunite with her father the Donna in this episode is played by TERI HATCHER
Hope that explains everything.
