Sanford ERVIN and Nancy MACE

Sanford's father is a William Ervin (b-abt 1855)

One match that I've found for William's father could be a Jacob Irvin found in the 1870 Vinton Co., Clinton Twp. census, where a William (b-1855) is listed as son to a Jacob and Christina Irvin:

Jacob Irvin, 50, b-1820, all born OH
Christina, 52, 1818
William, 15, 1855
Mary, 12, 1858
Margaret, 10, 1860
Sarah Ervin, 7, 1863
Hannah, 6, 1864
Daniel, 5, 1865
Isaac, 3, 1867
Alfred, 2, 1868
Alice, 5 mo. 1870

In 1880 we find this family in Ross County:

Jacob Irvin, 56, Laborer, all born OH, OH, OH
Christina, 41, Keeping Home, (Age not quite right)
Hannah, 18, at home
Daniel, 17, Farm laborer
Isaac, 12, Farm laborer
Alfred, 9, At Home
Alice, 8, At Home

1900 Vinton Co., Elk Twp., Dist. 108

William Ervin, Jun 1855, 44, OH, OH, OH
