According to my information Curtis and Rebeccah had 8 children total although several of them may have died in infancy or very young.
Martha Jane Duncklee b. 1827, Milford, NH d. 1888 Mariette Duncklee b. 1825 d. 1826 Nancy Alvira Duncklee, b. 1832 Milford, d. 1907 Horicon Martin Duncklee b. 1843 c. 1865 (possibly Civil War) He was born in Ticonderoga Hulda Duncklee b. 1840, Amherst, NH. May have died young Daniel Curtis Duncklee b. 1829 in Milford, NH d. 1901 Hezekiah Duncklee b. 1836, d. 1863 Cyrus Duncklee, b. 1847, may have died in infancy
I know that Nancy Alvira Duncklee were in Horicon, NY with her husband after they married in 1848.It is quite possible that Curtis and Rebeccah lived with or near them.From what I can tell, Nancy Alvira was the last surviving of Curtis's and Rebeccah's children.As I mentioned, Nancy Alvira Duncklee Bennett and her husband, Royal Zebulon Bennett were my gg grandparents.
