8 Apr 1745, along with his wife Bridget, John Avery sold to William Huggins of Greenland "all right & title that said William Huggins hath in possession that his grandfather's Nathaniel Huggins Sr. late deceased" - apparently young John Avery married Bridget Huggins.
Huggins or Higgins? Said to have been the daughter of Nathaniel Higgins and Sarah Haines.
