This is the tombstone of Georg F. and Eva Barbara Hoehamer, located in Mount Hope Cemetery, Adams County, Indiana. The marker is inscribed HOEHAMER on the front. The south side is inscribed:
Geb 4 April
Gest 20 Feb 1886
Alter 71 Y, 10 M
The north side of the marker is inscribed with the information of his wife:
Geb 16 Mai
Gest 9 Jul 1885
75 Y, 1 M, 23 T
The translations: Here lies Georg F. Hohamer, born 4 April 1814, died 20 February 1886, aged 71 years, 10 months, and 16 days. Here lies Eva Barbara, wife of G.F. Hohamer, born 16 May 1810, died 9 July 1885, aged 75 years, 1 month, and 23 days. [Note that Hohamer/Hoehamer was spelled both ways on the tombstone.]
I was pleasantly surprised and excited to find this marker in Mount Hope Cemetery. Before our visit to this cemetery I noticed the death and burial records of an older Hoehamer couple in Zion Chatt’s records. I wondered if they were Nicholas Hoehamer’s parents:
Georg Friedrich Hoehamer, born 4 April 1814 in Langenfeld, County Court Markt Bibart [?], District Mittelfranken, Kingdom of Bavaria, died 20 February 1866 in Adams County, Indiana. He was aged 71 years, 10 months and 16 days. He was buried on the 22nd.
Eva Barbara Hoehamer, born Strauss, born 16 May 1810 in Baudenbach, Bavaria, died 9 July 1885 in Jefferson Township, Adams County, Indiana. She was buried on the 11th.
I soon discovered that the older Hoehamers were indeed the parents of Nicholas (1845-1914). The marriage record of Nicholas Hoehamer to Delia Warner, his third marriage, named his parents as George F. Hoehamer and Barbara Straus.  Georg F. and Eva Barbara probably had other children, but I cannot be sure without doing quite a bit of additional research.
The tombstone of Georg F. and Eva Barbara Hoehamer is located one row west of their son Nicholas’ marker. In fact, you can see Nicholas’ tombstone in the photo above. It has the yucca plants growing around it.
The inscriptions on the sides of Georg and Eva’s tombstone were unreadable without a little tombstone cleaning. Fortunately I had my cemetery bag that contains my tombstone tools in the car. The south face of the stone was covered with a lot of green moss-type growth. I sprayed it down with my water bottle and rubbed the moss off with a soft nylon brush. I rubbed most of the moss off but left some moss behind in the chiseled areas. That made the letters and numbers readable.
I reflected a mirror on the north side of the stone and that was enough to make that inscription readable.
Georg and Eva Barbara were living in Springfield, Clark County, Ohio, in 1850. Their family in 1850: G.F., 43, laborer, born in Germany; Barbara, 40, Germany; Fred, 5, Ohio; Cath, 3, Ohio; Christina, 1, Ohio. These were probably their children, but you cannot be sure since relationships were not given in that enumeration. 
The Hoehamers had moved to Auglaize County by 1870. Their family in the 1870 census: Geo F., 56, farmer, born in Bayern; Eve Barbara, 60, Bayern; Margaret, 19, Ohio; George, 18, Ohio.  Living next door was their son Nicholas, 25, and his wife Anna (Manzelman), 18. Nicholas and Anna had married a few months before.
