Found on Findagrave1 and in other records. Unsure of where she goes on the Hagenbuch family tree. She could be a second wife or a wife of an unknown Hagenbuch. Where she shows up:
1894 Easton business directory as “Sarah Hagenbuch”: notes her as a widow and running a candy store.
1900 census: noted as being 56 years old and born July 1846 (seems she was probably 54 or born in ‘44). She was widowed and had been married for 10 years. She is living in Easton. It says she had 2 children, 1 living.
1901 will: signed in October of 1901 which is supposedly what is on the Findagrave tombstone. It mentions that she has a daughter Amey Raub. It is not clear if this is a married name. Sadie gives the daughter nothing and gives her things to her neighbors it seems.
1901 death records for Easton: Says she died October 11, 1901 and was 58 years old. It says she lived at 5th St. and Wolf Ave. in Easton.
