I have a Edward Kough b.1833 married Elizabeth R. Rugh. Edward is on the 1880 census as Edward Keough with his family. On the 1860 census he was listed with his mother Sarah Cough and Sister Sarah Cough and his father William Kough. He moved to Kansas sometime after that. There is another family that lives in Kansas that has the Kough surname. Edward on the 1880 census shows he was a coal miner in Westmoreland Pennsylvania. On his death certificate shows his father as a Kough and mother as a Milligan. Hope some one can help fill in this gap. Thanks
