My Gay family first appeared in Wisconsin in 1884. Thomas said he was born in 1858 in Illinois or Wisconsin depending on the source, and said his parents were born in Ireland. This means the parents had to be in the U.S. before his birth, but neither he nor they appear in the 1860, 1870, or 1880 census (that I can find). He is in the 1900 census. What other spellings should I be searching for?
