Recent findings for Abram CORYELL that was born in 1772 and died in 1854.  Because the children names seem to match earlier generations there could be a connection.  Abram 1772 had a son Abram II Coryell for which I have no dates so far.  Here is the information I have put together thus far.  The names come from bible records and family notes, you will find other names on the internet, but I am sure these are the correct names.
 Information came from Lowell S. Thomas March 25, 2001
