David has sent you the marriages so I won't duplicate that.
I found the following baptisms in St-Patrice, Marie-Reine-du-Monde, Rawdon, Quebec

James Churchfield baptized May 10, 1877 , son of John Churchfield and Suzanne McCabe. He was born the same day - sponsors were Thomas McCabe and Elizabeth Payette
I went to thecensus to see what other children were listed.I see in 1881 - John 46, Sarah 43 (I assume this is Suzanne) children listed are Stephen 18, Julia 16, John 14 and James 4 They are living in St. Theodore de Chertsey, Montcalm in 1881
I found baptism for Julia in Saint Patrick, Montreal
February 27, 1865 baptism, born on the 25th, daughter of John Churchill and Susan McCabe. Sponsors Michael Kelly and Ellen Goodwin
I did not find a baptism for son John
There is a marriage for Stephens Churchfield and Çatherine McPhilipps July 26, 1887 St-Alphonse-Rodriguez, Joliette, Quebec Stephen is a cultivator in St. Patrick, Rawdon, son of John Churchfield and Suzanne McCabe. Catherine is daughter of James McPhillips and Catherine Woods of the Parish where marriage took place.
There is also a marriage for a Suzanne Churchfield to Patrick Daley June 28, 1886 Saint Ann, Montreal. She is daughter of John Churchfield and Suzanne McCabe. Patrick is son of Charley Daley and Bridget Noonan.
** so either there is another daughter not shown in 1881 census or this is Julia - could be her name was Suzan Julia or Julia Suzan ??
There is also a baptism for a son Patrick Hugh Churchfield - Feb. 8, 1871 - St-Alphone-Rodriguez, son of John Churchill and Suzan McCabe. Sponsors John Shields and May Marlygin
