This John Giesler Sr was the father of Noah Giesler Sr born 1818 who married Sarah Eliza Harrison and moved to Missouri. She was a sister of William, Lewis, and Tyree Harrison. Do you have any info on these Harrisons, or names of any Harrisons that this Giesler family may have been neighbors-associates with in Tennessee prior to the move to Missouri? We have a Brick Wall in this Harrison line circa 1780-1820 in Tennessee, and are searching for the identity of the parents of Sarah Eliza Harrison Giesler and her brothers. Their mother is only identified as "Widow" Harrison in the few records descendants have ever found, father's name unknown. This John Giesler Sr and possibly his father Adam Giesler very likely knew the parents of Sarah Eliza Harrison Giesler. My direct email is geniebev2004@yahoo.com .
