if you can access Findmypast, there are several records under his name from 'Devon, Plymouth & West Devon Parish Chest Records'. They appear to be connected to the building of St Aubyn Chapel. The meetings were in his house, the Kings Arms, Fore Street, Plymouth Dock, Stoke Damerel.
One of the records from 1792 mentions the will & probate of Timothy. Under the terms of the will, John Baylay, the executor and residuary legatee, inherited seat no. 46 on the ground floor of the chapel. John made an indenture with Charles Jolly, shipwright, and John Gilbert, butcher, which assigned the seat to them.
