Was told by a fellow Carroll Researcher: this family came from Rockingham Co., N.C. around 1845 after Sarah Cantrell Carroll died.Sarah was the dau. of Jacob & Hannah Cantrell.William was the son of Henry Carroll. .. 1850 McNairy Co., Tn Census: William Carroll 60; Hannah 25; Henry 23; William 22; Daniel 20; Lucinda 18; John 16; Andrew 14. .. 1860 McNairy Co., Tn Census: William Carroll Mn 211-459; Henry Carroll Mn 210-458; W.P. Carroll Mn 211-459; Daniel Carroll, Lucinda Carroll Mn 210-458; A.J. Carroll Mn 211-459. So, Hannah Carroll had already married by the 1860 Census and couldn't find John Carroll in McNairy Co., Tn.Hope this helps.
