Hello both..... 

  Now that does look to be them.... I did not have an age for Mary just 1810 same as John her husband. Missed the death of George but that does add up as cannot see him mention on the listing.
  There are a couple of Mary Wood marriage in Strand
             Sep 1840 to John Grovener
                                 John Horlington
                                 Clement James
                                 Robert Lock   so I will see if any of those are mentioned
   I think the Dec 1839 ...same month as hubbies death is pushing it.
    Thank you both again see what this turns up.
