If you are my age, born in the early sixties in the northeast US, did you know more than one family with a pair of daughters named Lori and Lisa? Were they always in that order, with Lori first? Is there a cultural reference for it? Some book or movie or TV show with that name combination? I understand Lisa was the most popular girl’s name of the 1960s, but how would that account for an older sister being named Lori so often?
