I am looking for information on my g-grandfather Martin H. Covert, possibly called Mark. He was born abt 1857 in Ohio. He was found in both the 1870 census in Lucas County Ohio, Springfield Township in the home of his parents Edwin W. and Martha M. Covert, and in the 1880 census as head of household in Lucas County Ohio, Springfield Township. He was married twice, once to a Jennie Hopwood in Ohio and again to Elnora Margaret Sterling also in Ohio. Martin's father was listed as a blacksmith in Lucas County as was his father before him. Martin himself was a logger by profession and was missing fingers on one of his hands. Any information on any of the above listed would be greatly appreciated.
