I have information about a John McMackin b: 24 Aug 1809, d: 2 Feb 1894, Buried At Old Speedwell, TN. I am actually descended from his first marriage to Mabel Isabella or Isabella Mabel Bricker. To that union there were 5 Chidren: Mark Eagleton, Mariah Ellen, Minerva Elizabeth, James Bricker and Mary Melvina McMackin. In John's second family, he was married to Harriet Sliger. I have listed 9 children. From the dates of the births of those nine and Harriet's, it does not seem like she would have been the mother of all nine. She would have been nine years old at the birth of the first child. Family legend has it that John may have had as many as 20 children from possibly 4 different women. The nine children that I have are: Mary E, Ferguson S, Charlie, William W, Marion, Andrew Johnson, Sarah L, Warren and Samuel Frank McMackin. I have information that I will share with you. It appears that we probably have a match. I would be most interested in the information that you have. Hope to hear from you.
