I have a John Martin living in Horry County on the 1850 census. He was born in 1780,before the formation of Horry County (1802) He would have been considered living in Georgetown County at this time.
Who were his children? I am told that two were Isaac M C Martin born 1820 and Edith Martin born 1818.
Did he have a daughter named Mary Ann Martin born about 1827 who married a John N. Cannon?
Also, another son named Armstrong S H Martin born 1825?
If you have any information on these Martins please let me know.
