I have a Joseph Giltner who married Ophelia C. Daily from my family line. They lived in Clark County, Indiana which is just across the Ohio river from Gallatin County, Kentucky. Their marriage was in 1866. My Daily line was from Gallatin, Carroll and Trimble Counties. Some moved to Jefferson and Clark Counties of Indiana. My line moved to Missouri.
Not sure if you Giltners are in the same family, but there is a pretty high probability.
