Hi Peter
Daniel is a name I've often seen around my Hoeys but not one I've seen in the proven direct lines.
You said your Daniel was in the Royal Navy. Have you tried looking on line for the records? You may not have to wait until you can visit Kew.
I can't remember the details and the years covered, but there are various military records on Ancestry, findmypast and also covered by the uk National Archives catalogoe. If the record isn't online from the National Archives you can usual request an estimate and then a copy.
We do have an odd Edward in the cousins who went to London selling potatoes - I think he was a traveller. He went from Lancashire England, but later than your date - mid 19C.
Good luck with the search!
Best wishes
Emms
