    Would any of the brothers have the same type of ears that the SM had?

  2. Possibly might, who knows? It’s more interesting to chase down the possible DNA lines than look at ears any more, Clive, if only to escape your atrocious punning.

    Try this DNA line .. it’s the first of many.

    1/ Rachel has Thommo DNA, which could mean ..
    2/ She inherited them from her mother, Roma, which could mean ..
    3/ Roma is a Thomson. But we know she isn’t Prosper’s sister. So out goes that one, unless we go deep into her relatives and find another Thomson line.

    We try again.

    1/ Rachel has Thommo DNA, which could mean ..
    2/ She inherited Thommo DNA from her father, Robin, which could mean ..
    3/ Robin is a Thomson, which could mean …
    4/ He inhertied the DNA from his mother, Jessica, which could mean …
    5/ She’s a Thomson, but no sister was missing from the family, so ..
    6/ Robin inherited Thomson DNA from an unknown father and passed it on to his daughter Roma who passed it on to her daughter Rachel.

    How we going so far?

    # 6 A possible scenario? What’s the betting that Kate knows more about the Thomson family tree?

    • Byron D has handsomely allowed me access to an extensive Thomson family tree he created on Ancestry, and as a bonus, has let me into the Harkness line as well. A bloke doesn’t know where to start.

        Pro-tip: Online obituaries are family trees on a silver platter. Let’s look for Kate’s first cousins, since unfortunately it looks like Jestyn’s generation has all passed away.

    So, it may not have been a coincidence that Prosper just happened to stop Jessica from jumping off a cliff, according to a comment. Was Prosper being a gentleman or…?

    Is it outlandish to think that Prosper was actually Robin’s father? And that SM might fit in somehow with Jessica in some other way?

    Sounds like maybe Abbott’s head might be spinning because he’s basically found out that what he’s been selling isn’t the truth?

    “Derek Abbott and Colleen Fitzpatrick in 2015 – long before she discovered Thomson DNA in Rachel Egan”

    Um. Why “long before”. Sounds like bullshit spin to me. Surely, Colleen’s first request would have been for Rachel’s dna? They’re in there – all over the media – and haven’t run the basic tests? Nah.

    “Unconfirmed information is that a large Australian media network pulled the plug on a Somerton Man exhumation coverage at about the same time of Fitzpatrick’s startling news…”

    What’s “startling”? That Rachel may actually be Prosper’s grand-daughter? Why would that be “startling”? Why would they pull the plug? Maybe because the narrative they built up might have imploded?

    Could be wrong on all of this but it’s plausible.

    Sounds to me like they’re throwing it out there so to deflate a possible negative reaction to all the hype they have built up.

    So is the idea now that Jessica got pregnant with one of Prosper’s brothers and Prosper came to the rescue to give the child legitimacy?

    June 3, 2021
    • More like Prosper was the father who left his wife and settled in Adelaide with his pregnant girlfriend until they could get married.

    Sure. That too. But you don’t think it’s possible that he was actually the father of his pregnant girlfriend’s child? You think the father might have been a sibling or a relative of Proper’s instead?

    June 3, 2021
    • That’s two questions. Yes I do think it’s possible that PT was the father, and no to the father being a relo.

  8. Did your Rollo Thomson have a daughter called Miss Rollo Thomson who was an artist in Melbourne Australia. Our Miss Rollo Thomson painted portraits, one of which belongs to our very good friend and elderly Church of England Reverend Margaret Mabbs.

    • Mark: Rollo Thomson died in ‘43 according to Ancestry, leaving no children.

    I have been following this case for years. The simplest explanation is that Prosper Thomson was Rachael Egans grandfather. I am unsure why any other scenario is being entertained. She would not be the first child screwed up from being adopted. The idea that the Somerton man was her real grandfather needs to be put to bed. Still not sure why they dug him up given this information.

    • Stepheno, from what I remember, the SA govt agreed to exhume if Prof Abbott raised the funds to pay for it. I’m not sure how much of the 20 grand he collected but there’s no word of him refunding anything. I’ll say one thing though, changing the narrative is almost impossible .. every time the media throw up an article it’s copy and paste from stuff written ten years ago.

      Stephano…”Still not sure why they dug him up given this information.”

      I think the exhumation was worthwhile, considering the whole Webb family injection into the SM case is based purely on three hairs on the outside of a plaster cast that were ripe for contamination.
      At least, with the whole body, we’ll get a definite result. (If the authorities will ever be arsed to actually get round to testing the body, that is.)
