There could be two Elizabeth's married to Thomas Cason (b. 1604).There is showing an Elizabeth Alcott (acc. to a few researchers); and aa Elizabeth that had been married to: William Leighton, Thomas Cason, John Stratton & Jno Lawrence.
I do not have any vitals to prove this, I am looking at some of the other postings on this website including postings made on the CASON page, KEELING page and other pages dealing wtih different women who married into the Cason family.
If you have any insight or anybody else out there does, I would really appreciate hearing from you before I start collecting my own vitals or public records.
