George Sheeks married Matilda Puntney
I believe that George Sheeks of Genoa, Delaware County, Ohio married Matilda Puntenney/Puntney/Punteny/etc. Her Father would likely be Nelson Puntenny living in Blendon, Franklin Co. Ohio in 1830. This would explain where the Nelson name came from in later Sheeks.
Her brother Joseph Puntenny moved to Indiana and the 1870 census shows him born in Kentucky. I haven't been able to trace another brother, Nelson H. Puntenny yet. I found a Samuel Puntney of Logan County Kentucky(1810 census).
The name is apparently French, The legend on the Puntenny message board is that the name came over with General LaFayette during the Revolution.
I'll be doing more research on this, and I will update and correct this whenever I find more.
