Listed in the 1850 Sumter County, Alabama Census, there are three different William McGregors. William Turner McGregor (who once lived in Wilson Co., TN but can't find on TN Census records) was born 1799 in Tennessee. William McGregor was born Tennessee in 1815. William D. McGregor was born 1838 in Alabama. Can anyone researching this line help me determine how these McGregors are related? I have my hunches, but I have nothing to back them up with. Any help would be much appreciated. Thanks, Jenny
