Looking for information on John and Acha McMullen. I find them in the 1900, 1910 and 1920 Census and then they seemed to disappear.I do not see them in any burial records such as www.findagrave.com or the Onarga Cemetery transcriptions. I have John Empey or Empie born June 1861 in Illinois, his parents were John Empey and Margaret both born in Ireland.I have Acha McMullen, daughter of Robert William McMullen and Sarah Jane Pierce. Acha and John's children are Carrie born Oct 1885, Roy born October 1887, Lucy born April 1889, Edward born February 1894, Gladys born 1906 and Pearl Gertrude born September 2, 1892 who married George DeTurk Reiff. Any information would be greatly appreciated. Thanks.
