Posted with Mayflower tag as profile is Mayflower Project.
I will soon be adding a transcript of the will of a Rebecca Sampson to the profile indicated, from the image on ancestry.com. I believe it to be the will of the woman in the profile as the date, location, and names and relationships mentioned match the profile.
As that will not make any changes to the family, it doesn't appear to be a significant change, but rather provides corroboration to the existing dates and relationships. I.e., some children, grandchildren and spouses are mentioned by name and relationship.
Besides, it mentions (what appears to be) my g-g-...-grandfather. ;-)
