Her birth index:

SIMEON, ELIZABETH JANE     HOLMES-A-COURT  
GRO Reference: 1916  J Quarter in ISLE OF WIGHT  Volume 02B  Page 1192
__________________

In 1952 an Elizabeth Ratcliffe, aged 36, with Donald Ratcliffe, aged 5, travelled on the SS Q Elizabeth from Southampton to New York and stated that their Country of intended future residence was Canada.  She said she was a housewife.  They came from Hulets, West Witterne, Chichester [Sussex].  The ages make them almost certainly to be her and her second son.  Where was her husband and what had happened to her firstborn, Thomas?
_________________

ThePeerage.com says she divorced Thomas Arthur Ratcliffe in 1952.  This came from Burke’s Peerage, 107th edn of 2003, vol 3, p. 3623.

However this death with precisely the birth date given for her in 1939, looks as if she came back to this country and never re-married:

The image of the index page adds that his surname was Ratcliffe.

And this led to the matching page for Thomas Ratcliffe:

And this led to an uncertainty for the year: was it ’42 or ’43?
