There was a Jeremiah J. Dogan applied for pension in Kentucky 1833. J may be for John??
This Jeremiah moved to Indiana with his family.

Apr 20, 1819 James, David W. and Nathaniel were taxed on the same day.
March 14, 1820 Nathaniel and Hambleton taxed together on same day.
Mar 13, 1820 David and James taxed together on same day.

All of the early Dogan's apparently lived in Prince William Co., VA.
