There is some evidence that Mary Riley's maiden name was Duffy; she may have been a sister to Anthony Duffy and William Duffie (brothers who spelled their surnames differently).  Anthony came directly to Hancock County from Pennsylvania, but William was living in Washington County, Maryland, in both 1840 and 1850, and is said to have emigrated to Hancock County, Illinois, in 1855.

The obituary of John and Mary's daughter, Louisa, stated that the Riley family settled in Hancock County in 1855.  Their son, Martin, wrote of spending time with a cousin in Pennsylvania around 1856, when Martin would have been about 17.  Whatever the chronology, we know they were farming in Fountain Green Township, Hancock County, in 1860.  It's possible they were accompanied on the trip west by their grown son, William, and his young family, who were living near John and Mary in 1850 and who were in adjacent Hancock Township in 1860.

Mary died of typhoid fever on February 19, 1860.  See the Mortality Schedule for Fountain Green Township prepared with the 1860 Federal Census.  John survived her by a little over 10 years; he died August 2, 1870.  Both are buried at the Fountain Green Cemetery.

Also according to daughter Louisa's obituary, John and Mary had twelve children; we can document five of them:

i.	William Riley, born about 1825 in Pennsylvania, died March 24, 1866, probably in Hancock County, Illinois.  Burial at Fountain Green Cemetery.
ii.	John Riley, born about 1832 in Maryland.
iii.	Mary E. Riley, born about 1834 in Maryland.
iv.	Louisa Riley, born March 3, 1836, in the area of Hagerstown, Washington County, Maryland.  She died October 8, 1912, in Hancock Township, Hancock County.  She is buried at Moss Ridge Cemetery, Carthage, Hancock County. Louisa was the last surviving Riley sibling.
v.	Martin V. Riley, born about 1839 in Maryland, died in 1909 in Keokuk, Lee County, Iowa.  He is buried at Oakland Cemetery, Keokuk.
vi.	George W. Riley, born ca. 1843, in Maryland.  He died March 4, 1869, and was buried at Fountain Green Cemetery.
vii. through xii.  Six more Riley children.
