Jillaine, here is my summary on this.
This family group as it now appears in WikiTree seems to be a mishmash of many different and erroneous trees found at Ancestry, Find-a-Grave, and elsewhere. The Joseph attached as son is a real person, a Quaker from Amesbury later documented in Pennsylvania. Believed b about 1646 there is no documentation of his parentage and this date is nine years after the death of William Large of Massachusetts.
This familial relationship error is discussed by Anderson and it permeates the work of a number of genealogists and historians, thus the error is pervasive. The death date for Joseph in 1709 in Bucks is the date and location currently found (erroneously) o the profile of William Large (deceased by 1637). There does not appear to be record of another William Large who died 1701 or 1709 in Bucks. In many Ancestry trees the William Large seen as father of Joseph never left England, died 1689, and yet his son was born in Hingham, Mass. (Will continue next box)
