Biographies

I’m ask­ing for help from our Library God­dess­es for some­one on one of my mail­ing lists. She sent this request to the list, and I can’t find the answer:

“Back in the late 60’s when I was in sec­ond and third grade, I was addict­ed to a series of biogra­phies about US women. I don’t remem­ber what the series was called but the biogra­phies includ­ed Bet­sy Ross, Eleanor Roo­sevelt, Jane Addams, Clara Barton…all illus­tra­tions were sim­ple sil­hou­ettes. Now that I have three daugh­ters of my own, I would love to have these books for them (and to take a trip down mem­o­ry lane myself…) Does any­one else remem­ber these books and, if you do, would you mind steer­ing me in the right direction?”

Update: The series was Child­hoods of Famous Amer­i­cans. Thank you for your help!
