Remarkable resilience of a crew on voyage from Virginia to London
The resilience, courage and luck of some crews plying the Atlantic routes is well illustrated by the following excerpt from the testimony of a twenty-two year old mariner and ship's carpenter from Shadwell. The carpenter, William Welch, had returned to London from Virginia on the King of Poland through terrible winter storms in February 1655(56). The transcription is by Jill Wilcox.[1]
"1. to the 3: 4th 5th and 6th article of the sayd allegation hee saith that

8. day of ffebruary last in the morning the sayd shipp being with her
9. sayd Lading in her course for London and about the latitude of
10. thirty seaven degrees and a halfe and about ninety leagues to the
11. Eastwards of Virginia was surprized with an exceeding great
12. tempest the winds Blowing at west North west or thereabouts
13. with great furie and the sayd tempest continueing for fower or
14. fives dayes togeather the violence thereof drove in great seas into
15. the sayd shipp which raked her both fore and afte and split
16. and staved her longe boate all to peeces and breake the head of
17. her Rudder short off and soe brake the Iron works thereof that the
18. Rudder hung loose and was in continuall danger to bee wholly

24. perill of the lives of the sayd shipps company and eminent
25. danger of the losse of the sayd shipp and goods not withstanding

Nascent articles
PhD Forum members are invited to look at the MarineLives project exploration of C17th Arctic whaling, taking Batson and others con Gosling and others (1656 and 1657) as the starting point.
An article is being developed by several team members looking at the social structure of one of the whaling ships mentioned in this case, and the network of commercial and financial contacts supporting it. The project team is at the early stage of exploring the potential for something similar on the Virginia tobacco trade in the 1650s.
PhD Forum members are encouraged to contribute to either of these topics, and to explore the growing corpus of HCA 13/71 transcriptions for themes which might be suitable for further articles. All contributions will be acknowledged.

Themes
The following topics are currently being explored by the MarineLives project team in parallel with transcription work.
Each link will take you to a page which will introduce a topic and list a set of potential references in HCA 13/71, giving the title of the case and deposition, as well as a reference number. Electronic links are being added which will take you directly to the relevant transcription and manuscript image in MarineLives-Transcript/Scripto.
You are invited to explore these themes and to add your own comments and references as you browse HCA 13/71 online. You are also welcome to add your suggestions as to other relevant primary and secondary material, with the focus being on the 1650s.

2012-11-16 07:07:31 nbsp Welcome to John Gallagher, University of Cambridge, who is joining the MarineLives PhD Forum. John is a PhD student at Emmanuel College Cambridge, with research interests in language and communication in the Early Modern world --Users/ColinGreenstreet
2012-11-16 10:45:05 nbsp Check out some rough cut occupational and status analysis for the first 65 folios of HCA 13/71. In ff.1r-63v twice as many mariners as merchants deposed as witnesses. See Occupational and social status analysis of witnesses in HCA 13/71
You can look also look at the age data and occupation data for the different occupation and status groups
A full analysis to follow within the next couple of days --Users/ColinGreenstreet
2012-11-16 16:39:35 nbsp There is now an Occupational analysis worksheet, which is behind the Page Log in the online Google Doc Page Log and Planner you all have access to.
You might want to check out the latest version of this occupational analysis sheet. Data are in for f.1r to f.154v (so about 22% of total). There is double counting, which I will strip out by consolidiating individuals and allowing multiple columns to code for status, occupation, and job title. Nevertheless, I am surprised at how old some of the mariners are, and not just the captains, masters and commanders of ships.
The literacy analysis is very incomplete, since I have only currently captured signature vs marke for a relatively small number of the depositions, and someone will have to go back to all the images/transcriptions at the appropriate folio (we know where each deposition finishes, so it is not all 674 folios, and capture all the data onto the Page Log sheet.
Nevethless there is a high degree of basic literacy amongst mariners. Only a relatively small proportion of English mariners (often provincially based), and perhaps a higher portion of marine tradesmen and suppliers (shipwrights, coopers, butchers, watermen, labourers, and quite a high proportion of non-English mariners really having to leave their mark in the sample analysed to date.
You can explore the raw data yourself in the online Page Log. Use the Column J filter in the Page Log to look at signatures and markes, and the Columns K to M filters to look at occupation.
You can explore the sample of analysed data by using column filters for surname (Colimn B), age (Column C), literacy (Column D), occupation and/or status description (Column E), and five levels of location (street and building level, if available: Column G; parish level, if available: Column H; village, town or city: Column I; county or province: Column J; country: Column K). The raw data from which this is coded is reproduced in Column L). The underlying images for any case can be accessed through the URLs for the appropriate deposition in the Page Log.
Does anyone know of comparative data that exist for C16th, C17th and C18th by occupational group with a marine flavour, inclduing port trades? We will later be able to look at basic literacy rates for captains/masters/commanders vs other officers vs non-officers --Users/ColinGreenstreet
2012-11-17 13:55:26 nbsp Verbal and physical violence are a feature of a fair number of depositions. But it is rare for a ship to be lost as a result. But this was the allegation made by the gunner of the Fortune, who observed:
"the sayd Braining the Master without any provocation given him fell in furious manner upon the Boatswayn of the sayd shipp and with a stick or Cudgell knockt him on the head and wounded him very sore, to the endangereing of his life so as he became unable to give any assistance when the shipp was in danger"
See the new theme Violence and add your own contributions and comments. --Users/ColinGreenstreet
2012-11-19 14:34:55 nbsp I don't know if this is the best place to post this - it links to occupational and social status, I couldn't find a comment option there (showing the extent of my computer expertise...) but I can offer some comparative comments from my own research.
Vincent Patarino, in an article on 'religious shipboard culture', published in Fury, ed., The social history of English seamen (2012) (http://www.boydellandbrewer.com/store/viewItem.asp?idProduct=13786) has some figures across the seventeenth century, sampled from five files (HCA 1/9, 1/101, 13/64, 13/97 and 12/142), showing 37% of sailors and 63% of officers signing in 1603-30s, 93.6% of officers and 76.2% of sailors in 1650s-70s. In my own research, I have figures from the 1640s (HCA 13/56-61), pertaining only to London seafarers. 62-79% of these mariners, 87-94% of commanding officers, and 64-76% of other officers were signing their names (these represent the range of percentages from individual volumes). Literacy in London was probably higher than average, given the figures in David Cressy, Literacy and the social order (1980).
On age, I too was surprised to see how old a number of seafarers were, but I suspect this reflects the tendency for older and more experienced seafarers and officers to appear as deponents. From the same volumes, for London seafarers, only 40 per cent of deponents were under thirty; but over half of the sample were officers of some kind. This compares with a survey of London seafarers from 1629 in the state papers (SP 16/135, fos 111r-27v), in which only one third were officers and 56 per cent of all in the survey were under thirty. Unsurprisingly, the HCA are not a perfect census, although it does seem they are not actually that far out.
I think this raises two interesting points - firstly, how useful the HCA papers are for recovering details about early modern seafarers; and secondly, how careful we have to be about legal sources and whether they are truly representative. --Users/richardblakemore
