Hezekiah Robertson's tombstone reads: "In Memory of Hesakiah Robrson Died June the 19th 1852 aged 75 years". The family name has been spelled variously Robertson, Robinson and Robison. Also, the 1830 and 1850 census would indicate that he was born in 1784 not 1777 meaning he died at age 68 not 77. The "Robrson" spelling seems to indicate more of the way that Hezekiah pronounced his name rather than the way he spelled it!
