Thank you, JoAnn. I have Cornelia Dunham who married John Clark abt 1870. She was his 2nd wife/he, her 2nd husband. They had at least one child together, a son named Francis/Frank Clark b.ca 1874. She was daughter of Jesse H. Dunham and Susan Stanley. In 1880, they were in Chemung County NY. Am not sure what happened to their son? I cannot connect them to Binghamton at this point.
Are any of these given names connected with your photos?
