According to family history, my Grandfather, John Heffron Dearham, was born in Rock Falls, Whiteside County, on March 20, 1886, parents James Clark Dearham and Margaret Heffron. How would I go about verifying this information and obtaining a copy of his birth certificate? Also, are there city directories for that period of time? My great-grandfather was a butcher in Joliet, Will County, before marrying Margaret in Chicago in April 1885. Apparently, they then moved to Rock Falls where my grandfather was born. They had a daughter, Margaret Ann, born in 1887 but I don't know if she was born in Rock Falls. Thank you in advance for any help you can give me. Sue Murray, KY [email protected]
