Looking for help in locating any information about my great grandfather William Theodore Kuhlman b. 31 March 1854 in Madisonville, Hamilton County , Ohio and d. 13 December 1929 in Peoria Township, Franklin County , Kansas. He married Mary Caroline Markland b. 21 September 1852 in Ohio or Kentucky, d. 25 June 1908 in Norwood, Franklin County, Kansas. They married 28 April 1878 in Hamilton, Bulter County, Ohio. To this marriage were born Stanley Raymond (direct line), Harry Lee Morey, Rolland Edwin, Blanche Elinor, Emma Elizabeth, Grace Edna, and Bertha Alice Kuhlman. The two oldest children Stanley and Harry were born in Ohio and the rest of the children were born in Kansas.
According to family stories William's mother died when he was about two years old. His father remarried and he lived with his father and step-mother until he was 12 when he went to live with a B. B. Brinkman Family. At 16 he started working in a brick yard.
I have not been able to locate this Brinkman Family or William in any census records in Ohio. Can anyone out there help me locate William, his parents and siblings? Also looking for information about his wife and her parents and siblings. Her maiden name could have been Markland or Marklin and her parents could be John L. Markland and Mary Elizabeth Koontz.
