Record holder with most titles? (4,8)

'most titles?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'record holder with' is the wordplay.
I cannot really see how this works, but
'record' could be 'registry' (registry is a kind of record) and 'registry' is present in the answer.
'with' could be 'and' and 'and' is present in the answer.
A single letter 'l' remains which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
