I am researching my husbands family and have very little to go on in the Campbell line. His Great Grandfather was Clarence Joseph Campbell born in 1901 in Illinois, USA died 1970 and married to Ruth Sparks. I am looking for Clarence's parents. His father was named James and was born Oct 1862 in Ireland. James apparently came to the US around 1880 and married Lillie Florence O'Dell from Indiana. The only thing I know about James' parents is that they were both born in Ireland. I have checked passenger lists and other's family trees but have not found any other info.
