Share 'William Evans + Mary Lucey = Margaret Regina Evans (m. 1880 WI)'

I am looking for information on William Evans or Margaret Regina Evans. Here is what I have: William Evans + Mary Lucey = Margaret Regina Evans + Charles John Fitzpatrick (m. 1880 WI) = Cecelia Margaret Fitzpatrick (b. 1883 IA) + Carl William Cummins (m. 1911) Hope I can find a connection :-)
