So to explain it a bit more...this (see below) is how this lineage looks including the false parents attached to Jean Blanchard (b 1611) (the parents attached to him were in fact not his parents but they were his son Guillaume Blanchard and his wife, Jean's daughter-in-law, Huguette Gougon (aka Poirier) and her parents !
Guillaume Blanchard and his wife Huguette Poirier were married in 1610 in Martaize, France, she was born in 1590 in LaChausse. They were the first Blanchards in Acadia, now Nova Scotia, who arrived in 1640 from france. With them was their son Jehan or Jean and a daughter Marie, and Marie's husband Jerome Guerin. Jehan was born in 1611 in Martaize. Jehan or Jean married in Port Royal, Acadia in 1642 to Radegonde Lambert.
And this is how it should look like with the error (false parents) corrected:
Guillaume Blanchard , born 1651, was the son of Jean Blanchard and Radegonde Lambert. Guillaume married Huguette Gougeon (her stepfather or first husband of her mother was a Poirier so her halfsiblings were named Poirier, which is why she is seen a lot with the last name Poirier ), born 1657 and died October 18, 1717 in Port Royal, Acadia ( Nova Scotia ).
So we have it 'corrected', but we still (or again) have the (now seperated from Jean) false (in fact duplicates), and they all are set as unmerged matches now..
