That's very strange. When I click on any of the three links it opens the pdf ready to view or download. The url does start storage.ning.com, the site you reached, so I assume this is where Genealogy Wise stores the documents. I presume you have Adobe Acrobat so you can read pdf files? If it still does not work, I can send them to you directly if you send me your email address. Mine is email@example.com.
Welcome to the Whit(e)bread One Name Study Group on Genealogy Wise. When you enter the Group Page you should find an index of the various families. Your family is BDF_04, a very large family which we can trace back to Eversholt, Bedfordshire in the early 17th century. Having found BDF_04 there will be a link to that family's page. I haven't updated the files you will find there in a while, but you should find your family in it. Please let me know if you have any difficulties.
