If her husband Thomas was the one who was listed in the NEHGR 56:268 as having died on 04-10-1756, then his widow Susannah could be the one listed in NEHGR 55:262 as having married Barachiah Lewis on 12-15-1756 in Needham. Geni.com does list her name as Susanna Ockington Lewis (Everard). 
Geni.com does not indicate any marriages or children for her althought they do indicate two married names of Ockington and Lewis. And that Barachiah Lewis is quite a mystery with sparse information available about him. See the below link which leads to 12 generations of her ancestors.

Ancestry.com has he parents, two spouses, children and siblings. However, based on the dates of her parents, her mother was having children while in her 70's. Doubtful. Parents William (1679- 1765) and Rachel Newcomb (1678-1747) and their children (all born in Needham(Norfolk)MA: Susannah (1740-), Mary (1741-), David (1743-1822), Jonathan (1749-1832), Jonathan (1749-), John (1752-1752).

FamilySearch.org only did slighly better than Ancestry.com. However, the people involved are different. William Everard (1678-1765) and Rachel Newcomb (1678-1747) were married 1703-02-24 in Boston. They had John (1705-) born in Melbourn, England, William Jr. (1705-) born in Needham MA and is not indicated to be a twin to his brother John born the same year, Elizabeth 1709-1800), Rachel (1712-1770), Susannah (1714-1767), Sarah (1718-1795) and Peter (1721-1748). Per the dates given, Rachel Newcomb Everard would have been 43 when Peter was born. While possible, it is questionable. This also lists Susannah as having a brother Thomas (1749-1832) and says Susannah born 1740. However, from other sources, the Ockingtons has six children including a Susannah that was born and died in 1740. Susannah would have been 48 when the youngest was born. 
This record in FamilySearch.org went back seven generations for the Everards.
