Not really. Other than what I Could research on my own today. Lavender is not an uncommon name in England. To an Eric Frank Lavender is not out of the realm of possibility. I don’t know that is what the EF stands for. But again, the names ought to be rather easy to track down on an official level, buy employment records.
There will be other records in the area as well of such a person, other avenues of search other than just the Government.
