Hi Max I have completed the indexing of Crew list from National Archives BT 98/507 Port of Registry ~ Swansea Ships Names ~ A-G 1835-1844 and now started Crew list from National Archives BT 98/810 Port of Registry ~ Swansea Ships Names ~ A - Q 1845. Also so far completed West Glamorgan Archives 1862 to 1882 and 1890 to 1894. Indexing on going. The 1835-1844 are very porly kept records. In many cases they are not full names, but initials with surnames. Also the use of abbreviations like Jno and Jos. for John and Joseph. Surnames vary in spelling for the same mariner. Ages are sometimes left off. Place of birth are town names only and in some cases are not the same for the same mariner. Seamans Ticket No. very sparse. Previous ships missing, dates of joining and leaving are sometimes just he year or month and dates of leaving or arriving back into port are blank. I have had to interpret a lot of the data and hunt down ship arrivals to make sense of some of the crew lists. The crew lists are in boxes of rough alphabetic order and filed under Port Rotation No. There is some mis-filing, of ships from other ports especially where the ship sailed out on one register and arrived back on another. i.e Sailed as Sunderland ship and became a Swansea Registered ship and vice versa. Port Rotation No.s on my website have been interpreted into Port No.s for Swansea by referring the masters name on the crew lists and comparing it to thar on the Custom House Register, which contains the Master's name and subsequent master's date of appointment .Taking the master's name on the crew list and comparing it allows one to identify the ship especially when you have a ship called "Ann" and there are several in the box with rotation No's like 96/331 96/90 96/42 where 96 is the Port of Swansea and the other No's are rotation numbers referring to ships called "Ann" on the crew agreements. Many agreements are damaged and unreadable in parts. With the 1845, I now find they are in better condition and so far I have done A to B and they give the Port No of the ship and the Seamans Ticket No. and where registered with a date. Also the apprentices Indenture date and where registered. But one or two have missing ages, previous ships and dates of signing off. Signing on dates again in one or two cases only show a year. Again there are some damaged crew lists. Regards Bryan Richards www.swanseamariners.org.uk over 80,000 entries of mariners from the UK and other parts of the world who sailed on Swansea Registered ships, 1862 to 1882 and 1890 to 1894 and 1835 to 1844 complete. Crew lists for trawlers and Milford Haven also included and samples from other ports.
