Where do you get the info he died in 1900? For Campbell Duggan is found in 1900 in Collin COunty, Texas, with his second wife Mary Jane. Campbell Duggan is buried, per family sources I contacted at Forest Grove Cemetery in McKinny, Texas. Too many people get something off the internet, and don;t actually talk to family members. SInce that posting I have done extensive research and have found a lot of wrong information posted on him. It is true that he died between 1900-1910, but he left Sevier County in 1893, and moved to Collin County, Texas. He was married twice. Dicy died between 1885 and 1889, because his second wife had a child Lula born in 1890. I looked long and hard, but he is listed as CAMEL DUGGAN in Collin County, Texas, with second wife Mary Jane, and children Oscar, Charles, Roscoe, Bertie, Lula, and Lucy.
