Already, just from the preamble, OCT 01-4 shows firm evidence of fraud.
Before we get into the main body of OCT 01-4 it is perhaps worth a short detour to look at a name in that preamble: Princess Rowena Maria Elizabeth Overbeck McLeod of Austria. It is, to say the least, odd to find the names Overbeck and McLeod in a document dated 1764, even by the minimal standards of the Tallano canon.
Of course, ‘Princess’ might merely have been her given name. While not unusual in the present-day Philippines it would have been very unusual in the 18th century with its concern with rank and privilege. It may have been a rank acquired when she, if she existed, married the claimant to the throne of the Philippines, but that is unlikely since the ‘of Austria’ indicated she was a princess of Austria.
Two names are significant in the Tallano tale: Overbeck and McLeod. Only one of those has a link to Austria: Overbeck.
The sole Overbeck in Philippine history is a pharmacist’s son, But Overbeck cannot be named in any genuine document of the 18th century. The sole Overbeck involved in the Philippines in any way was Gustav Overbeck who negotiated a deal over Sabah with the Sultan of Sulu. He was born in 1830 and died in 1894. He was not of royal blood, was made a baron in 1864, did not visit South East Asia until 1860 at the earliest. And the female offspring of barons are not princesses.
What is left is McLeod. This is also problematic. According to documents distributed by Tallano claimants the McLeod name descends from a secret twin of Queen Victoria. The only McLeod to be significantly attached to Queen Victoria is the Reverend Norman McLeod who is alleged to have married Victoria and John Brown.
However, Queen Victoria was born on May 24, 1819, as would her twin have been if that twin existed.
The most connected McLeod in the Philippines was Neil McLeod, once head of Smith. Bell trading house in the Philippines who set up his own trading house, McLeod and Company in 1870 with another employee of Smith, Bell. McLeod & Co exported Manila hemp and sugar and was so successful it owned its own ships, some of them built specially for the company. It has no royal connections and certainly had no existence in the Philippines in 1764.
So, how do the names Overbeck and McLeod appear in a genuine document date 1764? The answer is that they cannot, and do not.
