Hi Karen,
In a word,no!

Their mother was Mary Corlis (nee Brophy) b.Halifax Yorkshire c1851 , this is from info on the 1881 Census, the only census on which the family appear together (RG11 4015/110 p20 - Howarth Street,Bradford,Manchester).I've not been able to find any BMD info for her.
Their father John Corlis b. Manchester c.1852, was a tailor (on all the birth certs). There is a John Corless/Carless on the 1901, 49 years old and a widow living as a boarder in Manchester, he is also a tailor,so is a likely candidate, but I can't be certain.
