He would have had to be born before 1870 if married in 1885. I have no births before 1870. Also no Andrew Annis births after 1870.
Did find an Andrew Annis in the Polk Co, IA state census 0f 1895 in Altoona Twp. Age 38, divorced. Living with Elsa 78 widow, Elisa 60 single -both born in KY. Andrew was born in Jefferson Co. IA. Living near George Annis 25 and Clark P Annis 47.
Most of the Wisconsin Annis' came to Wisconsin after 1850 from CT/VT and NY. Likely all related.
