Royal Descents

You may be a satisfied owner of The Royal Descents of 900 Immigrants to the American Colonies, Quebec, or the United States (RD 900), or you may be considering acquiring a set of these marvelous books.   Either way, you may appreciate the following suggestions from author and expert genealogist Gary Boyd Roberts on how to use the volumes. 

  • Check the surnames in your existing family tree against the index. It could turn up some surprising connections.
  • Mr. Roberts’ Introduction is 192 pages long, and it is the definitive summary of current royal and noble genealogy scholarship. Consult Appendix II of the Introduction, and compare your immigrant ancestors against those named in the Appendix.  You may discover an entire line you never dreamed of.
  • Look through the sources, especially for immigrants to the areas in which your family, or its branches, lived. You may wish to consult one or more publication you were unfamiliar with.
  • Go through any 50 or 100 pages in the text, and see some of the fascinating world figures you are/may be related to. If you have a favorite notable president, first lady, other politician, literary figure, statesman, or other popular figure you admire, be aware of them and see what surprises you can find.  See how much you have in common; one of them might be as close as a 9th or 10th cousin.  You might find a second or third cousin of someone you never heard of.  George Orwell, PG Wodehouse, Aldos Huxley are all there, and English people are as likely to find a cousin as Americans.


Among the many achievements made by Gary Boyd Roberts in his compilation of more than 900 lines of descent to Americans and Canadians in the two-volume RD 900 is the identification of 84 different monarchs who figure in those descendancies. In case you were wondering who they are, here is a verbatim listing of the first 17 and the last 15 of those kings, with mentions of their kinships.

  1. Dear Mr. Roberts –
    Thank you for this. I had the joy of speaking with you one eve on the phone – I’m a Taylor with Taylor angst because we cannot find my great grandfather’s line (probably from North Carolina to Mississippi (settled in Grenada). I would so much like to have a class with you. I live mostly in Uruguay and periodically come home to Memphis to re-fresh!!! and see my small family and wonderful friends. I’m an Anglican priest – first woman ordained in the Southern Cone of South America – and my ministry is mostly in prisons with incarcerated youth. My boost is doing the family tree and I now have almost 95,000 names on my tree. I work constantly – kin to just about everybody on Magna Charta, and most who came on the Mayflower (Yankee mom, southern dad – but small family.)
    I do wish you a generous Thanksgiving and a blessed Christmas because we are all kin to Jesus somehow, and God claims us all as his own, whether we know it or like it or not.

  2. I don’t have access to this book, but as one with considerable descent from 17th century mid-Atlantic Quakers, New England Yankees and Southern planters, I am astonished to discover absolutely zero royal descent whatsoever. None. Zip. Nada. Not one single “Gateway Ancestor” in my entire line. Perhaps I merely descend from a bunch of starving peasants who came here and made good, I don’t know. But I find it quite odd to have discovered not one trace of Royal lineage when so many of my ancestors were a part of the 17th century Great Migration to the South, mid-Atlantic and New England. Well, I hope to see your books someday if we are ever lifted from this long pandemic quarantine. Thank you!

    1. I suggest you drop a line to Gary Boyd Roberts, c/o The New England Historic Genealogical Society in Boston. Give him the names of a few of your earliest ancestors and ask him if he is aware of any royal/noble connections.

  3. Gary I think of you often while I’m researching. You helped me so much. I have over 7000 names now. A line to Mayflower and many famous people. Would love for you to come back and visit. I’m still stuck on my Smiths and Seymours. Only have them back to 1800. Ive used several of your books but when I buy one and loan it it’s gone. Lol

  4. Hello Mr. Robert’s. I hope this comment reaches you. I have 2 questions.
    1st one is in regards to Thomas Duke, who is mentioned in your book of 900 as a Gateway Ancestor to Edward IV. My 9th great grandfather is a Thomas Duke of Virginia. Your book shows he is an ancestor of the Duke Tobacco family and Doris Duke and they are in my tree. I am in a Duke study group with members who have thoroughly researched the Duke family for decades and they say our Thomas Duke is not the same one that’s in your book on pg 103 so your Thomas can’t be the one that is the ancestor to the Duke Tobacco Dukes. I cannot find online the source that you used in the book written by Christopher Carter Lee on the Dukes of Virginia.
    Question- how can I obtain a copy of that source? I’m willing to pay for it.

    2nd question- also in my Duke line at my 5th great grandparents, Clevears Duke and Amy Cosby. Her line traces to Francis Cosby who in your book says she married Mary Seymour, the daughter of Sir. Edward Seymour, the brother of Jane Seymour, the 3rd wife of Henry VIII. There are many who say Mary only had 2 husband’s and Francis wasn’t one of them. They quote sources on wikitree.
    Question- do you have any sources that show Francis married Mary Seymour. This is page 305 and 307 in your book.
    BTW- if it’s true about Francis Cosby and Mary, I have another line for your book that shows my 5th ggm Amy is a 3rd great granddaughter to Francis Cosby.
    My apologies for the length of this comment.
