John Halsam - Fake tree?

There are no referenced to be found on-line in Google Books to Elizabeth Hardman marrying Lawrence Halsam, nor is any Lawrence Halsam known in Haslam Hey. If he were from Haslam then he would be Haslam not Halsam. The tree is completely without any foundation, and there is no reference to be found that he died in Perche in France nor why he lived there and had children there. The descendants who supposedly ended up in America are equally unrecorded and the tre appear to be concocted. The only references are to trees on other websites, all copied from each other, and no sources.
