OK - will look forward to receiving the details. I gather from Hamish that you have all his relevant information too and that he is unable to place you in his branch of the family either!
No doubt that between us all we will get there one day!!!
I know that some of the early island newspapers gave lists of passengers alighting from boats at ports around the island, but this practice may have stopped before your dates - and, of course, it is arrivals in Liverpool you want - perhaps the Liverpool papers.... Next time I look at the newspaper fiches at the Manx Museum, I will have a quick look to see what level of detail may be available - and try the same in Liverpool (eventually)... but don't hold your breath too long!
