Brian, I looked through your family website and saw the Van Vickle I have been looking for -- George Washington Van Vickle. He married Mahala Ella Pontious in 1874 in Pickaway County, Ohio. I was able to locate them in the 1880 census -- living in Stanton, Miami County, Kansas. I had seen Mahala's death listed as 1/9/1925 in Americus, Lyon County, Kansas, so thought it was possible that they were in Kansas by the 1880 census. According to the census, Mahala was about 6 years older than George. They had a 3-year-old daughter, Martha E., born in Ohio; also another daughter, Harriet A., who was only 1 month old and listed as born in Kansas. So this Van Vickle family moved to Kansas sometime between 1877 and 1879. The family was listed under the surnam "Vanvicle".
Thought I would just pass this along. I am researching Mahala's father's family and was led to the Van Vickle name.
