Looking for Naliss Family

I am releated to the Naliss name - but I know very little of its origins.
My Great Grandfather James Dixon was born 16 Dec 1867 Helmsley, Yorkshire to a Sarah Dixon his father is recorded on the birth certificate as William Naliss - but James spent his life being called James Dixon.
But on his death (24 Jul 1934 Ecclesall North, Sheffield) he was buried under the name of Naliss - his death certificate gives his name as: "James Naliss - formerly Dixon)".
If anyone has any information on the NALISS surname and its origins - I think Ireland has been mentioned in the past - I would be very grateful.
