Benjamin and Philena have gone home!
However, the photos appear to have been taken in the late-1880's or early-1890's time frame. Based upon the apparent age of the subjects, my best guess for year of birth is around 1810-1820.
Benjamin was born in 1815 in Onondaga Hill, NY and died in 1900 in Syracuse. His wife, Philena Betts was born in 1825 in Bordino NY and died in 1903 in Syracuse.
Further internet research shows that they were the parents of 12 children: George Annable, Dwight Annable, Henrietta Annable, Elizabeth Annable Hutchings, Harriet Annable, Maria (Mary C.) Annable, Benjamin Annable Jr., Sarah Annable, Willis Annable, Ella Annable, Emma Annable, Leonard Annable.
