Digging For My Roots

I am entrigued by the young lady in this photo I found in my grandparents' photo album. She looks very much like my mother, but she's from a different era than my mother. She's not one of my grandmother's sister nor one of my grandfather's. I want to know who she is and more about her because I think she's lovely. Inside the old photo album, I found a crumbling newspaper clipping with this quote by Oliver Wendall Holmes: "We know the tenacity of certain family characteristics through long lines of descent and it is not impossible that any one of a hundred and twenty eight grandparents, if indeed the full number existed in spite of family admixtures, may have transmitted her or her distinguising traits through a series of lives that cover more than two centuries, to our own contemporary!" I would like to have some of her serene beauty.
Families are important. We're having a family reunion this weekend, as my parents move from the home they've lived in for the past 35 years.
