Confirming the Ephgrave and Kilby connections in the 1850s

I initially thought that Richard KILBY was the nephew or some other relative of Elizabeth EPHGRAVE, nee KILBY.  I've since found an IGI christening record which could be Elizabeth, for 17 April 1791 in Ayot St Lawrence in Hertfordshire, daughter of Richard and Jane KILBY.  Richard, I think, married Jane LAURENCE/LAWRENCE in Wheathamstead in 1812 (another IGI record).  Both of these need to be checked at HALS, but in the meantime I have found Richard KILBY's Last Will and Testament of 1826 (proved in 1842) at the National Archives' DocumentsOnline site.  This makes a clear link between Richard's daughter Elizabeth, wife of Thomas EPHGRAVE, and Richard KILBY.  All very exciting.  The legal hand in which these wills are recorded is a bit difficult to read, but my transcription looks something like this:
