Sarah Matilda Edwards was born February 16, 1870 in Nemaha County, Nebraska, the last of seven children born to William Edwards and Nancy Jane Rolston. Matilda's mother died in 1885 when Matilda was 15 years old. About 1893 Matilda married Charles Howard Blankenship. The couple farmed in Peru Village where one child was born between 1900 and 1910 but died within that same period. During that time, Sarah's widowed father-in-law, James William Blankenship, moved in with them. The couple retired from farming but remained in Peru Village. In the 1930 census the couple was enumerated with an adopted son, Thomas Petterson, age 19.
Sarah's husband preceded her in death in 1937. Sarah died in 1962 and was buried as Matilda Blankenship in the Mt. Vernon Cemetery in Peru, Nemaha County, Nebraska.
