I have (with the input of others) constructed my family tree back to about 1730 (one branch), and 1806 (another branch). All my family came from the small villages called the Rodings in Essex, UK - Abbess Roding, Beauchamp Roding, Leaden Roding and their surroundings. Most were illiterate agricultural labourers.
To download my complete family tree in GEDCOM format, please visit http://www.cus.cam.ac.uk/~jld1/Family/ (link below).
As part of my research, I have also built up partial trees of other families in Essex with the surnames Asser (Assur), Whitbread (Whitebread), Skinner, Claydon (Clayton), Manning, Reddington (Redington), and Blowes (Blows), mostly from the 1841, 1851, 1861, 1871, 1881, and 1891 Censuses of Essex. I'm looking forward to using the 1901 Census which will be available in 2002 - it should solve a few family tree problems!
