MILLICENT

Photo of adult believed to be Jo Hopper(Marshall), the back of the photo postcard says -
'Millicent Minnick at 5 weeks of age'

Last photo in a flea market ablum FULL of family history. This is Jo Marshall's 1922 ablum, per inside cover. Chronicals her marriage to J.F. Hopper in 1923, travels all over U.S., deaths, friends, family and this picture of Millicent Minnick and Jo. I don't THINK it's Jo's baby. Perhaps a niece? Can you help me get this heirloom to it's family?
