Mary, I certainly understand how confusing it is sorting out the various Tinney men with similar or identical names. Interestingly, I have seen no record of middle initials in use before the 4th generation.William Tinney, Sr. and his wife Matsilva settled in the part of Old Ninety-six District that would become Newberry Co. They were there prior to 1774.Their land was on Gilders Creek, a short distance from the town of Newberry. They had five known children: William, Jr., Richard, Isaac, Sarah, Polly and Nancy.I do not know what became of William, Jr. or anything about his possible descendants. The same is true for all the siblings except for Richard, who was my 4th great-grandfather.While I don't know anything about the Isaac E. Tinney you mentioned, he was definitely not the illegitimate son of Richard Tinney and Deziah Elkins. This Isaac, Richard's only child, left SC and settled in Gwinnett Co., GA before 1824 and lived out the remainder of his life there. He and his wife Susanna had 10 children and all but the oldest, Richard (named for his grandfather), were born in Gwinnett Co.All of the information stated above is well documented in the records.Is it possible that some of the information you have been given is about later generations with the same names?I will be happy to share my data if you wish.
