Reasearching STARLING / STERLING / STARLIN family ancestors in Northern KY counties of Gallatin, Carroll, Henry, Trimble. Trying to determine if the McLAUGHLIN and McGLOCKLIN mentioned below are infact the same family??

Sarah McLAUGHLIN m. John STERLING, 19 April 1821, Gallatin Co, KY
James McGLOCKLIN m Jane STARLING, 5 Jan 1825, Gallatin Co, KY

Any insight as to the family relationship of McLAUGHLIN and McGLOCKLIN family would be most appreciated.
