I continued searching a specific period (1/10-27/12/1843) in Brit.Lib.News'r archive under waterville then mills then antwerp with no other graphics in the search box and under antwerp came across this:
Liverpool Mercury 22.12.1843.
20.12.1843 Waterville, Mills, from Antwerp for this port at Stornoway, leaky and with sails split.
HT found an entry for Waltry Isle and I later came across a Water Lily so perhaps entries are being missed.
I rechecked for the period 20/12-23/12 as above and only antwerp produced a return. I then tried the first two followed by a comma and still nothing !!!! I'm not giving up yet !!!
From 8/10 at Falmouth, to Antwerp, at Stornoway 20/12, at Liverpool 27.12.1843.
No change yet to the possible BT98 ports to search.
