Dear Brooke,
Thanks. Good you questioned this!
Mistakes expand like rings in water. One person makes a mistake, and this mistake is then copied and pasted numerous times – sometimes hundreds of times.
This is what makes big genealogical sites such as Family Search, Geni and MyHeritage very dangerous sources.
Apparently, either Marlene A. Eilers Koenig or x Weir did their research with primary sources, and worse than that, they did not – opposite you – questioned their sources.
They apparently copied and pasted some secondary sources they found – without questioning this, and they did not either try to find primary sources or even get close to these (– and as we know now, both Burke’s and Debrett’s had it correct – even though they are secondary sources). Afterward, they charged money for their poor – or should we call it non-existing – research results, which were actually just based on “copy and paste”.
As I have mentioned earlier, I had an intermezzo with Marlene A. Eilers Koenig a little over 20 years ago, when I, as a history student (next to my normal work and a corporate SVP at a large global group), contacted her:
I questioned politely something she had written, which I believed was wrong, but instead of embracing my correspondence, Marlene A. Eilers Koenig acted arrogant and impolite, informing me about her academic and scientific credentials and telling me that I had no entitlement as a student to question her authority in these matters.
Instead of answering my questions, Marlene A. Eilers Koenig referred me to buy her book, which we now know is made as “copy and paste” – and is therefore, in reality is a “shortcut” coffee table book – and not a book based either on academic research or scientific evidence, and I will so far to say, that her book cannot be called independent work, and I wonder how many more copy and paste mistakes her books includes(?)!
Best regards, Nick
P.S.
It is for this reason that Nordic universities still use Professor, D.Phil. Kristian Erslev’s book 100 years (1926) after the last edition was published. Primary sources will always be the foundation for history studies and you should always question your sources!
