Genealogy Help. Need searching for Gneht/Knechts of Columbia County, Pa?

I need help finding information on Harvey D. Knecht, born May 7, 1862, in Catawissa, Columbia County, Pennsylvania. His wife Harriet and him had 6 children. He died on July 10, 1956 in Williamsport, Lycoming County, Pa. I know he lived a large part of his life also around Williamsport, Lycoming County. I have found him in the 1880 and 1920 censuses. I have found both spellings, Gneht and Knecht. I am particuarly interested in finding more information about his parents. If you come across anything, email me at chrisginpa@yahoo.com. Thanks for your help.
