#156: my oldest (half)sister -- aka my dad's first daughter Carol Ann -- in 1965 (according to the writing)
#157: this has to be my aunt Evelyn's son Michael S (aka my first cousin since Evelyn was my dad's sister), and the date on the back says Oct '66
#158: my dad's parents Esther and Paul (my paternal grandparents) and a mystery couple standing in front of, as it says on the back, "the site of Lincoln's Gettysburg Address, PA 1968")
#160: a postcard from someone named "tommy", who was apparently on a trip to Wales and sent a card to my dad's parent Esther and Paul (my paternal grandparents) about how he was in the town "where his father was born"
