Have you looked at Peter Lowe b. 1859, living with Peter and Rosanna Lowe, in the 1870 census in Shelby County, Missouri? Glover's death certificate at http://www.sos.mo.gov/archives/resources/deathcertificates/Results.asp?type=basic&tLName=lowe&tFName=glover&sCounty=all&tYear=1915#null says his father was born in Audrain County, and that's where Peter Lowe lived in 1860:
Year: 1860; Census Place: Prairie, Audrain, Missouri; Roll: M653_606; Page: 796; Image: 300; Family History Library Film: 803606.
Year: 1870; Census Place: Tiger Fork, Shelby, Missouri; Roll: M593_806; Page: 125A; Image: 253; Family History Library Film: 552305.
There's a couple Peter (also born 1859) and Mary E Lowe in 1880. Another researcher has her as Mary Ella James, which jives with http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=88027210. I can't find a marriage record. Anyway, they're in the right place at the right time.
