That the wife of William Comstock was named "Elizabeth" is from:

• "25 Jan 1659. William Comstock of New London deeded 8 acres in New London to Will Houge, carpenter, with consent of wife Elizabeth." [Note: C. B. Comstock quotes the deed as "with the consent of my n ow  wife Elizabeth". Some researchers have interpreted this to mean that William Comstock had more than one wife, but the expression "my now wife" in legal terms at that time in New England only meant the wife, not that there had been a previous wife.]
• a court record that stated Elizabeth Comstock was aged 55 in 1663, which would give her a birth year of 1608. (History of New London?)

That her last name was Daniel(s) appears to originate from: Hi story of the National Society of Daughters of Founders and Patriots of America,  for the fifteenth year, ending May 13, 1913, Mary Ella Comstock (Mrs. Carl J. Vietz) gives the wife of William Comstock as Elizabeth Daniels-- as cited in A History and Genealogy of the Comstock Family of America,  page 2.

Torrey's New England Marriages Prior to 1700 (p . 175) says:
Comstock, William(1) & 1/wf [?Elizabeth Daniel?]...

If she was a Daniel, she may have been sister to Robert Daniel who settled in Watertown, then Cambridge.

That Elizabeth Daniel(s) was daughter of Henry Daniels is from  Some Descendants of William Comstock by Kay Haden (2008), which includes:

• Correspondence with Lee Daniels in 2002. Her ancestors were John Daniels, b. abt 1640 in Weymouth, England who moved to New London in 1666 and married Mary Chappell of New London. Mary's sister was Abigail Chappell who married John Comstock, son of William & Elizabeth.  She had found a Henry Daniel in Much Hadem who had a daughter Elizabeth Daniels, born 8 Jan 1607/08 at Culmstock, Devon, England.  She believed William Comstock was also from Devonshire and they had married circa 1622. Henry Daniel was born 1582 at Much Hadem, the son of John Daniel & Elizabeth Pebite of Kelshall, Hertford, England.
