Thanks for your note. This is definitely "our" Edward Dulian, and we have very comprehensive information on the Dulian line from his arrival in Christian County to the present day. William Dulian cited in the 1910 census is my grandfather.
Thing is, we don't know much about him *before* he shows up in that census. The surname Dulian seems not to exist before 1870. We believe that Ed Dulian ran away from home as a relatively young boy, adopting this spelling probably as an expedient for the census (he was illiterate) in place of whatever he was born with. Information developed since I posted that inquiry leads to the hypothesis that he was the son of Patrick and Marcella McDonnell DOLAN of St. Louis, but Doolen/Dulin/etc. is still a possibility, since the surname Dulian is pronounced DOO-lin by most of the present-day family. Any leads before 1870 would be appreciated; please e-mail me, as I seem unable to mail you.
Incidentally, we have reason to believe that his host at the time of the 1870 census was also the victim of a spelling error/change; the family name is almost certainly Clendenin, even though some other Christian County records, not just this census, use Clendien. We know a little more about this family, which was somewhat ill-starred.
