Mary Lucas was daughter of Sir John Fermor of Eaton Neston in Northamptonshire [1]and his wife, Maud Vaux.
She married Thomas Lucas, son of John Lucas of London and Colchester, and his wife, Mary Abell.[1] They were parents of two sons and three daughters. [1]
Research note: In a Google search of Mary Fermor, I found the scholarly looking website: "Dennis Lundahl's Genealogy Site." person page 37422 https://our-royal-titled-noble-and-commoner-ancestors.com/p3742.htm#i112380. This website cited the following Gerald Paget book as its source # [S11572] for their displayed information about Mary Fermor (approximate birth date and place, and her death date and place) and family (parentage, etc). I have been unable to view the book so far. But I am continuing to investigate interlibrary loan possibilities.
