Hi Rita, william connor married(24 apr 1870) mary CALLAHAN OR CALLAGHAN that's the correct spelling of her maiden name. These two spellings are pronounced the same the g is silent. When you found your william's marriage did you see the thomas connor who married susan mccann(14 may 1865)? Have you checked the 1878 history of will county that is up on the will county site for any info? Kathy Zavada
