I have checked my records and there is a William James Manners born Clifton (York ?) Sept quarter18686a 80hopefully the birth certificate may give you a little more information. I have no listing in my database for his father although I did find a Thomas who married in Hull march quarter 1856 (9d 287) so the mothers name may give you a few more clues. He may also had siblings Sarah Ann born Sept q 1857, Frederick Charles born Sept q 1859 ( who is listed as dying June q 1864) and I have noticed several more children listed as born in Clifton including another Frederick hence my looking for the death of Frederick Charles. There is therefore a possibility that one of the grandparents were Frederick. The general information is purely speculative and is deduced from the BMD index register, the only way to be sure is to buy the certificates; fortunately there was not any other Manners as listed in the Hull /Clifton areas during this period which helps.
I would be interested if you establish a link to the family if you need any more help let me know.
Best of luck
PS I have just checked and his mother may have been Louisa Howell and his wife's maiden name was Sarah Elizabeth Weatherley
