I don't want to add too much to your confusion, but there are still queries as to whether these burials are your relatives.
I can't rationalise why the Florrie we have found, if she was her child, was not buried with her mother but in another cemetery.
I'm also confused (doesn't take much these days) as to why there are burials in consecrated and unconsecrated ground. If this was the same family, wouldn't they be one or the other?
I understand how they possibly ended up in separate places if the authorities took care of things.
I'm going to suggest that you contact Leeds Bereavement Services, I rang on your behalf

cems.crems@leeds.gov.ukIf you give them the names, dates, cemeteries and plot numbers they may be willing and able to look in the cemetery registers and look for other informtation that hasn't been transcribed. The council should have ledgers with name and address information as to who paid for the burial plots, although they are in a public or common grave, someone still had to pay but not for the exclusive rights to that plot. What has been transcribed and put online appears to be daily lists of burials not ledgers.
