I am looking for birth records for my father and his 2 brothers and sister.

My father is Alton Desford Annis born July 11, 1888 the records i have found disagree as to the year, he was born in poke county wisconsin.

His parents names; Edward H. Annis and Maybell Jane
the records has many spellings "Belle" "May" "Maybelle" "Mabel")

His siblings; Norris Annis born in 1879, Lewis George born in 1884, Eva born in 1890 may have been born in another state.
