THE EVANS FAMILY AT KIRKHAMS BRIDGE!

I am trying to trace John Evans in Staffordshire England before 1880.He arrived in Manitoba at that time accompanied by his daughter & son in law Minnie & Joseph Kirkham,& also a daughter Sarah.Sarah had a daughter Mary Evans born about Jan. 1881.Sarah married someone named Heathcote and lived in or near Buffalo N.Y.
Mary married Harry Cash presumably of the same area,She had two sons Harry and Sidney.Nothing further is known!
William Evans (son of John)arrived in 1882 from Biddulph Staffordshire with his wife Mary Ellen Shallcross and two small children Bertha & Joseph Information on these people prior to this would be appreciated!
