Ground breaking research by Sonia St.John in her January 2024 news article entitled "Events Come in Threes" - Unveiling Margaret Beauchamp and identifying two missing generations.
Her article reveals that YDNA analysis of St.John DNA results proves the documented St.John family tree (available to members of The Friends of Lydiard Park) is correct beyond all reasonable doubt. Thanks to contributing research by Friends' member Greg Shepherd, the article also reveals that St.John ancestress Margaret Beauchamp (c1409-1482) was the 13th great granddaughter of King William 1st of England.
