This doesn't answer your question but did you notice the Hattie Scofield listed under Jessie Moore in the 1870 census? That Hattie Scofield married Seba R. Beach, Josephine Joslyn's sons (Wesley, Wilbur and Eddie) are living with Mrs Harriet Beach in the 1900 US census for Winchester. The attached 1909 obit for Wesley Joslyn mentions the aunt and an uncle Rev F. S. Scofield of NY City.
The 1917 obit for Hattie A. (Scofield) Beach mentions that she was born in Wappinger Falls, NY and was the SISTER of Mrs Charles Moore.
