If this is the same Rebecca Jane Fulford born 25 FEB 1868 Monroe Co IN; then she's the dau of Jonathan Hawkins FULFORD born 9 SEP 1836 Monroe Co IN died 5 FEB 1890 and his 2nd wife Spicey A Hacker born 7 MAY 1843 d 11 FEB 1922. i have Spicey's obit. Rebecca would have had 9 or 10 brothers and sisters and two half-brothers. Do you need thier names?
If these are them, then i also have Rebecca's parents,grandparents and great-grandparents families on both the Hacker's and Fulfords. Her father Jonathan H Fulford was 1st married to Spicey's sister; and three of his sisters married Hacker's, brothers of Spicey.
Not sure when or where i found this but i have her married 8 OCT 1887 to Frank YORK. Would your Ben F. York's middle name possibly be Frank?
