I believe this is Hattie and Walter Fletcher, the pencil on a dark card is difficult to read.
I will guess this Cabinet Card was taken around 1880 give or take a few years.
I think the photographer is H.S. BealsThanks for stopping by. Do come again.

Update from Iggy:
I think this might be Willard Franklin Fletcher's family. He and his wife Lulu had Hattie S., 14 (in 1880) and Willie F. 10. Willard (Mar 1835 - 1924) was the Chief of Police in Oakland, CA.
