I am aware of earlier posts regarding a Thomas Morrell, age 63 (bn c1787), in the 1850 SullivanCo census. The following deed indicates there was an even older Thomas Morrell in SullivanCo. The following mention of Thomas would indicate he was born before 1780 if he owned land in 1801. If Thomas bn 1787 was the son of the older Thomas, the older Thomas would likely have been born before 1767.
