When I learned that George Hiram Thoma of Garnavillo, Clayton County, Iowa used an alias as a young man, it took me by surprise. He was born to Fred and Matilda (Hammond) Thoma in 1880,1 and the state census indicates that he remained in his home county in northeastern Iowa at least until 1895.2 At some point thereafter, according to family lore, George left home and bicycled across Iowa. Whether he went by bicycle or not, it was said that his move may have been spurred on by his poor relationship with his father.3

Records place George across the state in northwestern Iowa on 23 March 1902, at which time, using the name George A. Neilson, he married Anna Leota Fenton in Ashton, Osceola County, Iowa.4 This was no trick of penmanship or recorder’s error; three affidavits, written by George, his mother, and his younger brother, were attached to the marriage document decades later, each attesting to the fact that George A. Neilson and George Hiram Thoma were one and the same person.5 It is worth noting that George still named his correct place of birth and even the correct names of his parents on the original marriage document, with the exception, of course, of assigning the Neilson surname to them as well.6 Evidently, he was not prepared or had no reason to invent an elaborate backstory regarding his origins.
None of the affidavits, however, explained why George had married under an assumed name.7 One has to wonder whether his wife even knew what she was getting into! Prior to his marriage, I suspect that he might be found in the 1900 U.S. census as George Thoma, a clerk in Belden, Cedar County, Nebraska. Notably, he boarded with a family by the name of Nelson, and a Nielsen also resided in the household.8 Although this may or may not be the correct George Thoma, we do know that within weeks of his marriage, he moved to Center, Knox County, Nebraska, where he was an employee of the Edwards and Bradford Lumber Company.9
Within a few years of his marriage, George relocated with his family to Sioux City, Woodbury County, Iowa. There, his daughter’s birth was recorded with the surname Neilson,10 and according to the city directories, George continued to use his assumed name at least until 1909.11 I have been unable to locate the family in the 1910 U.S. census – they had likely left Sioux City by that time to return to Nebraska, where they moved from place to place for the next decade. However, they had certainly reverted to the use of the Thoma surname no later than World War I.12
Was this alias purely symbolic, in order to emphasize George’s separation from his father, or, perhaps, the ties that he forged with another family? Or was it part of an effort to hide, whether from his father, from love, or from the law? This is one family mystery that I would love to solve!
