Hi Kirsten
He's not on the list of Liverpool Pilots.
Master Mariners were Masters (or Captains) of Merchant ships trading either in the Home or Foreign trade. Knowing that he was on a ship called the 'Enderley' could be of some help in your rsearch.
You could try Google or this site which gives advice on searching for Master Mariners
www.mariners-l.co.uk/UKMasters.htmlFor my own part, my GG Grandfather was a Master Mariner c1800. I have experienced extreme difficulty trying to trace him, or his birthplace, until last Friday when I visited the NRO at Kew. There I found an entry for several voyages he made between 1836/1840 and the ships that he sailed on. Well worth the journey from the North West.
Best of luck
Dave
PS perhaps you could post on Rootschat but be more specific, such as:-
Help!! Ship 'Enderley', the year, Captain Alexander Dill and see what replies you receive.
