This photo of Tony and his human A. M. Almy, (as written on the back), was taken in Sandwich Illinois.
In the 1900 census, we find in Bristol Illinois:
Andrew Almy age 44 born Rhode Island
Lucy Almy age 40
Harriet Almy age 23
Cora Almy age 11
Bristol is only 13 miles from Sandwich where the photo was taken.
In the 1930 census Andrew used his middle initial of M. and that along with his residence in 1900 leads me to believe he is likely the man in this photo. Andrew and Lucy had moved on to Michigan by 1930, he died later that same year in Michigan. I've been unable to trace Tony.
