Dear Pasdlm
Again, thank you, and, well, a new twist to the tale, is that very recent family discussion has resulted in a memory that Thomas Aitken, en route to the Cape, South Africa, to take up his first posting as a Baptist Missionary, departing the UK, possibly August, 1896, was actually, 'shipwrecked' onto the Island of St Vincent, Cape Verde Islands!
Therefore St Vincent, Cape Verde Islands, might never have been his intended destination.
I wonder if and where, there might be records on Cape Verde, of mid-19C Christian Missionaries?
If indeed, Thomas Aitken, was 'shipwrecked', it could explain his quite short period, on St Vincent, as a Missionary, i.e. from September, 1896 - March, 1897?!
