I'm sure the cemetery index is complete but the dates you mention cover the period when the West Cemetery was operational.
It's very odd though that you haven't found anything in the birth or death registers. Are you sure you have the right surname as they would be your mother in law's father's uncles (phew). I've always got to write that down to make sure I've got the right names in the right generation. Presumably the uncles could have been from the maternal or paternal side of her father.
