Regarding the death of Elizabeth, what we do know is that her son in law Joseph Daniel, husband of daughter Lydia, acted as her attorney in collecting on her behalf from the estate of her brother Abraham who died in December of 1711. We presume, then that she died no earlier than 1712.

There is much discourse on the wives of Deacon Jonathan. His first wife is most likely Joanne Close. It's also probable that they had three children before she died in England and subsequently he immigrated in about 1650 to Weymouth, MA and later to Medfield.

Some SECONDARY sources would indicate an Elizabeth Fussel as his second wife. The theory is that she was a stepsister * of Deacon Jonathan who both married Deacon Jonathan in 1665, gave birth to her first child at age fifty and died the same year. The preponderance of evidence indicates the unlikelihood of this having been fact. There are no birth, baptism, marriage, death or burial records for anyone named Elizabeth Fussell Adams.

*Jonathan's widowed mother, Edith Squire Adams, had married a neighbor named John Fussell. In one secondary source Jonathan is referred to as living with and as being "son-in-law, (ie stepson)" of John Fussell. In 1650 and long after that (till 1850) the term "in-law" indicated a stepchild/stepparent relationship. This term in an old source does not provide proof of anything beyond the stepson relationship.

"Answers to Genealogy FAQs - Meaning of in-law

Whether "in-law" is applied to son, daughter, brother or sister is not important. What is important is the customary use of the term "in-law" as it was used to describe the relationship of various members of a family throughout the past centuries. The term "step" did not come into 'common' usage until the late-1850s and even then it took awhile to really catch on as a relationship description.  By the time of the 1870 census most true "step" relationships were being recorded as such. There were exceptions, though.

Prior to that time, the term "in-law" was routinely used to signify a child who was the biological child of one partner only. Thus, if a woman had children from a previous marriage then her children would have been known as the husband's child - signifying that the child had become part of the wife's family by the operation of law. Conversely, though, if a man had children from a previous marriage then his children would have been known as the wife's child"-in-law" in her Will should she have survived her husband."

Therefore it's probable in the absence of documents showing the existence of an Elizabeth Fussell and the use of the words "ie:stepson" that the biographer was not naming Jonathan Adams as John Fussell's daughter's husband but in fact simply his stepson.
