Challinor-Challender Horwich Lancashire

I have John Challinor born1865....Thomas born 1867..George born 1869..Mary Jane born 1871..and Gerrard born 1877 all born in Horwich...except Gerrard who was born in Wigan. On the 1901 census their name was spelled Challender. Does anyone have these people? I really need to know the fathers name. Mother is Betty ??? born 1840 Charnock Lancashire. I need her maiden name also.Anything is appreciated on my dead end.
