Presidents and First Ladies Trivia

[L Verge]

Congratualtions Laurie.
I Googled Ida McKinley, but I didn't see a good rememblence in any of her photo's I found.

I used my knowledge of clothing styles to try and figure it out. The first photo's neckline gave me some hints (as did the tinting of the cheeks) that led me to think late-1860s. The second photo's dress style was a dead giveaway as to being ca. 1860. Combining the two guesses put me in the 1870 range, and I started from there.
