I'm posting two photos I saw on an online auction site (if I list the name, Rootsweb will remove this post). I thought someone researching this family might want to see the photos. I'm not the seller and I know nothing about the photos - sorry.
I did a search on Ancestry.com and found Lottie on the 1880 census in St. Louis.
