This is Frances E. Noonan, who was 8 months old when this portrait was photographed. There is a date provided, 3/4/1918, but it's unclear if this is her birth date, or the date of the sitting. The photographer's name is embossed in the lower left corner: "Williams, Broad & Erie Ave." Using the streets mentioned, I've tried to identify the city in which this photo was taken. Perhaps it is Philadelphia, but it could be a number of other locations as well.
I searched for Frances E. Noonan in some of the genealogy databases without finding anything I considered a firm possibility.
Have you any leads to send my way? I'd love to hear from you.
