His WW I draft registration card, filed 12 Sep 1918, records Wilbur Augustus Sellers, age 20, address 469 Taylorsville Rd, Hillsboro, Montgomery Co., Illinois, born 27 Nov 1898, occupation running coal stock, employer C.C.C. & St. L. Ry Co, nearest relative Lerena Sellers, same address.

The 1900 census listed him as age 2, born Nov 1896, which is inconsistent. But his sister Katie was listed as age 7 months born Oct 1899, so it is unlikely that he was born in Nov 1898.
