Hi mo-jo
Please could you give more details about what you already know?
Is he the James with Alice in the 1881 census? You probably need to find their marriage first and get the certificate to find his father's name and occupation, as I can't see him the earlier census in Guernsey (he may be away at sea in 1871) and those details would help to find him in 1861.
To help find the marriage you may first need to get one of the children's birth certificates, to find out his wife's maiden name, unless you already know that.
