Sorry about that, forget about the Liverpool's Registers of Visiting Vessels. I just noticed a note I made log ago:- All British cvessels visiting Liverpool for the first time were entered in a series of Registers (10 in all), the data being copied from the ship's copy of the Custom House and Register of their parent port. When in 1824 ship register system was introduced, all the pre 1824 registers were transfered to the new system. Most ports threw out the old registers, but some retained those absolute records and some still exist. In fact I see that in this file I only recorded data from 1790 to 1798. So your best bet is still for the "Bills of Entry", unfortunately those I have on file are running from 1822 to 1858 only.
