A 1998 map of portions of Elba and Hamilton Townships of Gratiot County, Michigan, overlaid with the location of the 1889 property of Samuel Hatfield (N43° 09.83' W84° 23.41').  This may be where Samuel’s second son, Clarence Frederick Hatfield was born in 1889.

The map also shows 1889 properties owned by Samuel’s brother, John Hatfield (N43° 11.06' W84° 29.01'), and L. E. Criss (N43° 11.168' W84° 28.933') which was probably where John Hatfield was living in 1880 as a border and saw mill hand.  This was possibly where John met his future wife Mertie Sinclair as the 1880 census shows her living in the same house, as a servant.  John and Mertie Sinclair Hatfield were married in Elba Township Aug 15, 1880. Mertie Sinclair was the daughter of Hason Sinclair, one of the first residents of Gratiot County and his 1889 property can be seen in Hamilton Township, just north of the township line with Elba.  The L. E. Criss mentioned is probably Lucian E. Criss who married Hason Sinclair's older daughter, Ida  M. Sinclair, and she is probably the wife, as listed in the 1880 Elba Township, Gratiot Co., Michigan residence where John P. Hatfield and Mertie Sinclair are living.

There is also an Ira J. Sinclair who owns property in Hamilton Township, Gratiot Co., Michigan very near the property of Hason Sinclair.  This is probably Ira James Sinclair, Hason Sinclair's son, who was born in 1866.  

Note: Even though Mertie is shown on the census with the Criss family in 1880, she is also listed along with her two brothers, Michael and Ira James, as living with her parents.  It is also peculiar that the Hason Sinclair residence is listed on that census as being in Elba Township of Gratiot County even though in 1889 it was located just across the north township line into Hamilton Township.
