Hi again Sandra,
I just arrived home and opened an envelope from GRO containing a birth certificate... saw the headings... and it struck me: does your death certificate say, "Registration district: Barrow upon Soar", "Sub-district: Rothley"?
If it does, then the Recovery Home was probably NOT in Barrow upon Soar itself--Barrow had its own subdistrict. The Rothley subdistrict covered a large area of Leicestershire, including Woodhouse (where a Cheshire Home is now found, which in the 1960s was a children's convalescence home... don't know about before that), and Belgrave which is now part of the general Leicester urban area.
I did a quick web search, but could not find a Recovery Home just by searching in Leicestershire. Does it give any other indication of the address at all on the certificate?
Another source you might try:
