This collection contains a client ledger and separate index from Sir Matthew Barrington's legal firm in Limerick city, providing names of clients and details of the legal affairs in which they were involved. The ledger, originally part of a multiple set of volumes, is of considerable historical interest in view of the distinguished client list, which includes both nobility and prominent merchants, and the level of detail provided of their legal affairs.

This small collection contains routine correspondence and accounts created and generated by Maxwell, Weldon & Co. on behalf of their clients, mainly pertaining to probate, death duties and other testamentary matters.
