Often times we as genealogists put a lot of trust in legal documents and for the most part they are accurate. However, in this case with Marilyn Monroe not including the strong circumstantial evidence but now clear DNA evidence it is erroneous to think of Edward Mortensen as Marilyn Monroe's biological father. Gladys Pearl Monroe obviously listed his name on Marilyn's birth certificate to avoid scandal and the fact that Stanley Gifford did not wish to be the father of Marilyn. The DNA evidence looks solid and from very reputable, skillful experts in their field, especially when it comes to DNA and hair analysis. Had this been some upstart DNA company, amateurish and with little experience I would have my doubts.
The other night I viewed the documentary on Marilyn Monroe, Her Final Secret, which was released in France but the English version was now shown in Australia. The professionalism and experience of the scientists of the laboratories in Huntsville, Texas and in Toulouse France leaves little doubt.
I was able to watch this documentary in English on SBS Australia. Overall, it was very professional with very reputable geneticists and scientists conducting the research. I think it was very sound research, 22% of her genome decoded. and revealed a three generation connection between Francine Gifford and Marilyn Monroe using the text lines from their DNA. Several statistical methods were used to compare and verify the final results. They definitely chose the right scientist for the job, Ludovic Orlando, PhD in Paleogenomics, an expert in extracting DNA from ancient hair samples. . It was kept secret from him as to the identity of the hairs until the final results were made. Until the revelation of the hair belonging to Marilyn Monroe the samples were identified as 'Hair Girl'.
I also want to mention that two sets of saliva samples from Francine and Lisa Deir (I'm not certain if Lisa is the daughter of Francine Gifford or a niece of Francine. Regardless, she is still the great granddaughter of Charles Stanley Gifford and also submitted her DNA), and Marilyn Monroe's hair samples were sent to two different laboratories. The hair sample from Marilyn's hairdresser, Robert Champion, was sent to a DNA laboratory in Huntsville, Texas, north of Houston. This research facility is capable of deciphering damaged DNA in human or body hair. Dr. Rachel Houston is a research geneticist. Dr. Houston is also an active member of the American Academy of Forensic Sciences (AAFS) and the Association of Forensic DNA Analysts and Administrators (AFDAA). Her other research interests include exploring the use of alternate DNA markers (INNULs, INDELs, SNPs) and Massively Parallel Sequencing (MPS) for human identification (HID) and intelligence purposes. After DNA extraction from this sample was made it was useless yielding no results. This is fairly common with DNA in the keratin of the hair where what little DNA there is it is probably damaged. DNA resides mostly in the roots of the hair.
The second hair sample came from Marilyn's embalmer, Allan Abbott,. This was sent to Centre for Anthropobiology and Genomics of Toulouse (CAGT) lab dedicated to deciphering old DNA located in southern France. Head researcher, Ludovic Orlando, PhD in Paleogenomics headed this project. His experience, includes deciphering DNA from hairs of a 50,000 year old woolly mammoth. and hair from a 700,000 year old horse. It was this sample of Marilyn's hair that yielded results from which sequencing could be conducted and a link made back to the common ancestor (Charles Stanley Gifford) of Marilyn Monroe and Francine Gifford Deir and Lisa..
Getting back to the research done by Ludovic Orlando, PhD in Paleogenomics at the Centre for Anthropobiology and Genomics of Toulouse, France. He stated that the results of 22% of Marilyn's genome showed a three generational difference between Francine Gifford Deir and Marilyn Monroe. This confused me because Francine would be the niece of Marilyn Monroe and that would be only one generational difference. But then it dawned on me. Marilyn Monroe was Francine's HALF Aunt. They both descend from different mothers. This means according to the cM (centimorgan) chart the amount of cM for a half aunt and a great grandparent are about the same, in the 870-880 range on average. A great grandparent would be three generations away from Francine. Obviously, Marilyn could not be Francine's great grandparent which leaves only one other option, Marilyn was Francine's half aunt. The amount of this cM fits perfectly in the half aunt category. The likelihood of a false-positive would be 1 in 46 billion. Ludvovic Orlando was extremely fortunate to find the very small amount of Marilyn's DNA within the keratin of her hair but it was all that was needed to establish 22% of Marilyn's genome, and as Ludovic stated, make it irrefutable that Charles Stanley Gifford was the biological father of Marilyn Monroe.
