Hi I have information on your GG Grandfather Larkin Oscar Knick.
My husband David Carol Knick is from the line of William and Melinda Welchhance. His Great Grandfather was James Leferrett.
Our cousins found in their research that Melinda (B.abt 1822) and Mary Ann (B.abt 1825) Welchhance were sisters. Their parents are William Daniel Welchhance and Charlotte Hostetter, marriage January 7, 1817 in Rockbridge, Virginia. We have Charlotte parents and grandfather's name. William and Melinda married September 4, 1838 in Rockbridge County, Virginia. They moved to Washington County, Tennessee, where the Welchhance's were already living. William and Melinda then moved to Murray County Georgia and Mary Ann came with them. On the way from Tenneesse to Georgia how ever long they traveled, Larkin Oscar was born.
It looks like they all lived together in Georgia.
Melinda filled for divorce on Tues. April 21, 1863. William and Mary Ann applied and received a marriage license on April 21, 1863 and were married two days after the divorce was final. They were married on April 23, 1863. Our cousin has a photo of William, Charlotte and and the two daughters Melinda and Mary Ann.
Would love to share any information with you!
