Mary Elizabeth Rampton (c.1868) was the daughter of James Rampton (1848-1931 / born in England) and Susan F. Worden (1843-1886 / Pennsylvania, USA)
Mary would be my 3rd Cousin 2x removed.
I have her living with her family per the 1880 US Federal Census in Danville, Worth, Iowa.
James Rampton was the son of Charles Rampton (1816-1889) and Charlotte Tibbel (1816-1885). Both born in Hampshire County, England and died in Michigan, USA.
I don't have any info on Susan Worden's family, although in the 1860 US Census a Susan F. is living with parents David and Mary in Roulette Township, Potter, Pennsylvania; along with 2 younger children.
Hope this helps!
