My latest article has just been published in The American Genealogist also known as TAG. It is my 28th published article of which I would say 14 or so are major articles. It is my first English origins article, that is, placing a 17th century immigrant to New England back in his/her home parish in England, in this case William Dudley (1609-1684). I think it is an OK article. However, before I could read it, due to the vagaries of the U.S. mail, others had read it and had already emailed me about it--some positively, some not. I started with a thesis that was inspired by an article in TAG. I extracted all the primary sources for Dudleys in Dorking, Surrey, England and assembled the family there, I believe, for the first time. The key to the article was seeing that an Eleanor Dudley was not a daughter but a widow when she married and tracking down her will. I used the process of elimination method, showing that of four possible William Dudleys, two had no records beyond their childhood, one clearly stayed in Dorking, and the last was demonstrably alive but far away from Dorking. Yes, it would have been nice had either his mother or brother said in their wills: he's in New England, but that happens far less than one would hope for. In the same issue of TAG, there in another English origins article where the will of a father doesn't note the son in New England either. It is a combination of other wills that make the identification possible. In any case, I think the article is correct in its identification. I fear I may have transcribed one name incorrectly. The 16th century handwriting in the parish register which I viewed on microfilm, was tough. I saw Gooder. It may have been Hooker. I'll have to go back and relook at the registers again.
No one teaches you how to do genealogy. It isn't one skill, but hundreds of skills based on ethnicity, time period, country, religion, etc. The paleography (handwriting) of medieval and late-medieval England is at present the bane of my existence as I push into that area.
