No, not related ... just doing South Australian ship's captains and their families as a local resource. Many mariners here are very difficult to trace here due to the state of records, access, lack of indexes, etc. Transcripts of South Australian births, deaths, and marriages do make it easier ... but errors and name variations add other complexities. Paritcularly with Littlely, which tends to be garbles more than not. Also of the Captain's children some were born interstate, etc.
I've been in contact with one of the descendants of the Capt. John Littlely, who is a member of the Genealogy Society here in Adelaide.
Most of what I've posted up previouly however has been slotted together, but it is probably better that I email the full details rather than post it on the forum. Click on the contact address.
