Gray or Grey family

Hi

I am researching a family from Starcross. Particularly three brothers Grey of Gray who tragically drowned in the Isles of Scilly in their vessel called Plenty in December 1840. The vessel was owned by Thomas Parker of Topsham. The captain was Robert Gray (sometimes spelt with an E). This must hopefully have been recorded since it was a significant tragedy. I am trying to find a professional researcher who could help me. I believe the wreck site may have been discovered. If you can lead me to someone it would be very much appreciated
